2007-02-19Add "isodow" option to EXTRACT() and date_part() where Sunday = 7.Bruce Momjian
2007-02-19Fix pg_dump on win32 to properly dump files larger than 2Gb when usingMagnus Hagander
binary dump formats.
2007-02-19Parse pg_proc.h with entries without OIDs.Magnus Hagander
2007-02-19Get rid of some old and crufty global variables in the planner. WhenTom Lane
this code was last gone over, there wasn't really any alternative to globals because we didn't have the PlannerInfo struct being passed all through the planner code. Now that we do, we can restructure things to avoid non-reentrancy. I'm fooling with this because otherwise I'd have had to add another global variable for the planned compact range table list.
2007-02-19Improve plpgsql's error message when a datatype declaration is omitted.Tom Lane
Per example from Jeff Ross.
2007-02-19Put function expressions and values lists into FunctionScan and ValuesScanTom Lane
plan nodes, so that the executor does not need to get these items from the range table at runtime. This will avoid needing to include these fields in the compact range table I'm expecting to make the executor use.
2007-02-18Fix portal management code to support non-default command completion tags forTom Lane
portals using PORTAL_UTIL_SELECT strategy. This is currently significant only for FETCH queries, which are supposed to include a count in the tag. Seems it's been broken since 7.4, but nobody noticed before Knut Lehre.
2007-02-17Add code so that when COPY_PARSE_PLAN_TREES is defined, the copy andTom Lane
equal functions are checked for raw parse trees as well as post-analysis trees. This was never very important before, but the upcoming plan cache control module will need to be able to do copyObject() on raw parse trees.
2007-02-17Remove rint() for to_char MS and US output. We can't us rint() becauseBruce Momjian
we can't overflow to the next higher units, and we might print the lower units for MS.
2007-02-17Cleanup of to_char() patch.Bruce Momjian
Brendan Jurd
2007-02-17Create AVG() aggregates for int8 and NUMERIC which do not compute X^2,Bruce Momjian
as a performance enhancement. Mark Kirkwood
2007-02-16Teach find_nonnullable_rels to handle OR cases: if every arm of an ORTom Lane
forces a particular relation nonnullable, then we can say that the OR does. This is worth a little extra trouble since it may allow reduction of outer joins to plain joins.
2007-02-16Fix new RI operator selection code to do the right thing when working withTom Lane
an opclass for a generic type such as ANYARRAY. The original coding failed to check that PK and FK columns were of the same array type. Per discussion with Tom Dunstan. Also, make the code a shade more readable by not trying to economize on variables.
2007-02-16Reduce the amount of memory "clobbered" for every process title change,Bruce Momjian
on platforms that need this. This is done by only writing past the previously stored message, if it was longer.
2007-02-16Adjust the definition of is_pushed_down so that it's always true for INNERTom Lane
JOIN quals, just like WHERE quals, even if they reference every one of the join's relations. Now that we can reorder outer and inner joins, it's possible for such a qual to end up being assigned to an outer join plan node, and we mustn't have it treated as a join qual rather than a filter qual for the node. (If it were, the join could produce null-extended rows that it shouldn't.) Per bug report from Pelle Johansson.
2007-02-16Better fix for determining minimum and maximum int64 values that doesn'tPeter Eisentraut
require stdint.h and works for "busted" int64.
2007-02-16Install a more correct fix in the timestamp and timestamptz regression tests:Alvaro Herrera
remove duplicated tests in timestamp, and complete timestamptz with the tests that were missing to more closely mirror timestamp.
2007-02-16Code review for SSLKEY patch.Tom Lane
2007-02-16Fix the timestamptz test problem, by moving the tests that use theAlvaro Herrera
timestamp_tbl table into the timestamp test. Also, restore a test that used to exist as a valid test in the timestamptz test.
2007-02-16Fix // commentPeter Eisentraut
2007-02-16Add stdint.h includePeter Eisentraut
2007-02-16Functions for mapping table data and table schemas to XML (a.k.a. XML export)Peter Eisentraut
2007-02-16Fix another problem in 8.2 changes that allowed "one-time" qual conditions toTom Lane
be checked at plan levels below the top; namely, we have to allow for Result nodes inserted just above a nestloop inner indexscan. Should think about using the general Param mechanism to pass down outer-relation variables, but for the moment we need a back-patchable solution. Per report from Phil Frost.
2007-02-16Add two new format fields for use with to_char(), to_date() andBruce Momjian
to_timestamp(): - ID for day-of-week - IDDD for day-of-year This makes it possible to convert ISO week dates to and from text fully represented in either week ('IYYY-IW-ID') or day-of-year ('IYYY-IDDD') format. I have also added an 'isoyear' field for use with extract / date_part. Brendan Jurd
2007-02-16SSL improvements:Bruce Momjian
o read global SSL configuration file o add GUC "ssl_ciphers" to control allowed ciphers o add libpq environment variable PGSSLKEY to control SSL hardware keys Victor B. Wagner
2007-02-16Remove useless database name from bootstrap argument processing (includingAlvaro Herrera
startup and bgwriter processes), and the -y flag. It's not used anywhere.
2007-02-16Restructure code that is responsible for ensuring that clauseless joins areTom Lane
considered when it is necessary to do so because of a join-order restriction (that is, an outer-join or IN-subselect construct). The former coding was a bit ad-hoc and inconsistent, and it missed some cases, as exposed by Mario Weilguni's recent bug report. His specific problem was that an IN could be turned into a "clauseless" join due to constant-propagation removing the IN's joinclause, and if the IN's subselect involved more than one relation and there was more than one such IN linking to the same upper relation, then the only valid join orders involve "bushy" plans but we would fail to consider the specific paths needed to get there. (See the example case added to the join regression test.) On examining the code I wonder if there weren't some other problem cases too; in particular it seems that GEQO was defending against a different set of corner cases than the main planner was. There was also an efficiency problem, in that when we did realize we needed a clauseless join because of an IN, we'd consider clauseless joins against every other relation whether this was sensible or not. It seems a better design is to use the outer-join and in-clause lists as a backup heuristic, just as the rule of joining only where there are joinclauses is a heuristic: we'll join two relations if they have a usable joinclause *or* this might be necessary to satisfy an outer-join or IN-clause join order restriction. I refactored the code to have just one place considering this instead of three, and made sure that it covered all the cases that any of them had been considering. Backpatch as far as 8.1 (which has only the IN-clause form of the disease). By rights 8.0 and 7.4 should have the bug too, but they accidentally fail to fail, because the joininfo structure used in those releases preserves some memory of there having once been a joinclause between the inner and outer sides of an IN, and so it leads the code in the right direction anyway. I'll be conservative and not touch them.
2007-02-15Restructure autovacuum in two processes: a dummy process, which runsAlvaro Herrera
continuously, and requests vacuum runs of "autovacuum workers" to postmaster. The workers do the actual vacuum work. This allows for future improvements, like allowing multiple autovacuum jobs running in parallel. For now, the code keeps the original behavior of having a single autovac process at any time by sleeping until the previous worker has finished.
2007-02-15Add ORDER BY to a query on information_schema.views, to avoid possibleTom Lane
platform-specific result ordering. Per buildfarm results.
2007-02-15Repair oversight in 8.2 change that improved the handling of "pseudoconstant"Tom Lane
WHERE clauses. createplan.c is now willing to stick a gating Result node almost anywhere in the plan tree, and in particular one can wind up directly underneath a MergeJoin node. This means it had better be willing to handle Mark/Restore. Fortunately, that's trivial in such cases, since we can just pass off the call to the input node (which the planner has previously ensured can handle Mark/Restore). Per report from Phil Frost.
2007-02-14Make it possible to build with integer datetimes in msvc, and enable by default.Magnus Hagander
2007-02-14Fix to_date()/to_timestamp() 'D' field for day of week, was off by one.Bruce Momjian
Converting from char using 'D' doesn't make lots of sense, of course. Report from Brendan Jurd.
2007-02-14Move fsync method macro defines into /include/access/xlogdefs.h so theyBruce Momjian
can be used by src/tools/fsync/test_fsync.c.
2007-02-14Fix capitalization and punctuation of two more GUC description strings.Neil Conway
2007-02-14Fix up foreign-key mechanism so that there is a sound semantic basis for theTom Lane
equality checks it applies, instead of a random dependence on whatever operators might be named "=". The equality operators will now be selected from the opfamily of the unique index that the FK constraint depends on to enforce uniqueness of the referenced columns; therefore they are certain to be consistent with that index's notion of equality. Among other things this should fix the problem noted awhile back that pg_dump may fail for foreign-key constraints on user-defined types when the required operators aren't in the search path. This also means that the former warning condition about "foreign key constraint will require costly sequential scans" is gone: if the comparison condition isn't indexable then we'll reject the constraint entirely. All per past discussions. Along the way, make the RI triggers look into pg_constraint for their information, instead of using pg_trigger.tgargs; and get rid of the always error-prone fixed-size string buffers in ri_triggers.c in favor of building up the RI queries in StringInfo buffers. initdb forced due to columns added to pg_constraint and pg_trigger.
2007-02-13Disallow committing a prepared transaction unless we are in the same databaseTom Lane
it was executed in. Someday it might be nice to allow cross-DB commits, but work would be needed in NOTIFY and perhaps other places. Per Heikki.
2007-02-13Improve postmaster's behavior if an accept() call fails. Because the serverTom Lane
socket is still read-ready, the code was a tight loop, wasting lots of CPU. We can't do anything to clear the failure, other than wait, but we should give other processes more chance to finish and release FDs; so insert a small sleep. Also, avoid bogus "close(-1)" in this case. Per report from Jim Nasby.
2007-02-13Add code so database scans are done in an order consistent withBruce Momjian
pg_dumpall.
2007-02-13Add ORDER BY to vacummdb so databases are scaned in the same order asBruce Momjian
pg_dumpall.
2007-02-13Un-break build on ANSI compilers (like msvc) by moving Assert to positionMagnus Hagander
after variable declarations.
2007-02-13Add script to run regression tests under vc++ without mingw. UpdateMagnus Hagander
clean script to properly clean up the result of it.
2007-02-13One more fix for makefile := to : change.Magnus Hagander
2007-02-13Properly parse Makefile after change from := to =.Magnus Hagander
2007-02-13Repair bug in 8.2's new logic for planning outer joins: we have to allow joinsTom Lane
that overlap an outer join's min_righthand but aren't fully contained in it, to support joining within the RHS after having performed an outer join that can commute with this one. Aside from the direct fix in make_join_rel(), fix has_join_restriction() and GEQO's desirable_join() to consider this possibility. Per report from Ian Harding.
2007-02-13Add comment to explain why O_EXCL and O_TRUNC can be ignored inBruce Momjian
openFlagsToCreateFileFlags() in certain cases.
2007-02-13Add comment that to_char() for broken glibc pt_BR might cause a problem.Bruce Momjian
2007-02-12Avoid infinite recursion when dumping new planner EquivalenceClass trees.Tom Lane
2007-02-11Add support for optionally escaping periods when converting SQL identifiersPeter Eisentraut
to XML names, which will be required for supporting XML export.
