2003-07-09Add special checks for non-super-user setting LOG_MIN_DURATION_STATEMENTBruce Momjian
to zero.
2003-07-09Add new USERLIMIT GUC source level so certain options can be disabledBruce Momjian
or increased only by super-users. This fixes problems caused by making certain variables SUSET for security reasons.
2003-07-04tm2timestamp should return -1, not elog, on overflow. (In the backendTom Lane
this is merely an API inconsistency, but in ecpg it's fatal.) Also, fix misconceived overflow test in HAVE_INT64_TIMESTAMP case.
2003-07-04Add --help-config facility to dump information about GUC parametersTom Lane
without needing a running backend. Reorder postgresql.conf.sample to match new layout of runtime.sgml. This commit re-adds work lost in Wednesday's crash.
2003-07-04Some early work on error message editing. Operator-not-found andTom Lane
function-not-found messages now distinguish the cases no-match and ambiguous-match, and they follow the style guidelines too.
2003-07-03Fix bug I introduced in recent rewrite of NUMERIC code: numeric toTom Lane
integer conversions gave the wrong answer for values with stripped trailing zeroes, such as 10000000.
2003-07-03Do honest transformation and preprocessing of LIMIT/OFFSET clauses,Tom Lane
instead of the former kluge whereby gram.y emitted already-transformed expressions. This is needed so that Params appearing in these clauses actually work correctly. I suppose some might claim that the side effect of 'SELECT ... LIMIT 2+2' working is a new feature, but I say this is a bug fix.
2003-07-03Code review for UPDATE tab SET col = DEFAULT patch ... whack it aroundTom Lane
so it has some chance of working in rules ...
2003-07-01Aggregates can be polymorphic, using polymorphic implementation functions.Tom Lane
It also works to create a non-polymorphic aggregate from polymorphic functions, should you want to do that. Regression test added, docs still lacking. By Joe Conway, with some kibitzing from Tom Lane.
2003-07-01Dept. of second thoughts: supporting inlining of polymorphic SQL functionsTom Lane
takes only a few more lines of code than preventing it, so might as well support it.
2003-07-01STRENGH => STRENGTH, per Jon Jensen.Tom Lane
2003-07-01Department of second thoughts: even if we can't run the full parser onTom Lane
a SQL function with polymorphic inputs, we can at least run the raw parser to catch silly syntactic errors.
2003-07-01SQL functions can have arguments and results declared ANYARRAY orTom Lane
ANYELEMENT. The effect is to postpone typechecking of the function body until runtime. Documentation is still lacking. Original patch by Joe Conway, modified to postpone type checking by Tom Lane.
2003-07-01Change EXECUTE INTO to CREATE TABLE AS EXECUTE.Peter Eisentraut
2003-06-30Add GUC option log_error_verbosity to control which fields of errorTom Lane
reports get put into the postmaster log. Options are TERSE, DEFAULT, VERBOSE, with the same behavior as implemented on the client side in libpq.
2003-06-29Restructure building of join relation targetlists so that a join planTom Lane
node emits only those vars that are actually needed above it in the plan tree. (There were comments in the code suggesting that this was done at some point in the dim past, but for a long time we have just made join nodes emit everything that either input emitted.) Aside from being marginally more efficient, this fixes the problem noted by Peter Eisentraut where a join above an IN-implemented-as-join might fail, because the subplan targetlist constructed in the latter case didn't meet the expectation of including everything. Along the way, fix some places that were O(N^2) in the targetlist length. This is not all the trouble spots for wide queries by any means, but it's a step forward.
2003-06-29Information schema views for group privileges, some corrections on columnPeter Eisentraut
privileges.
2003-06-29It was comparing the wrong pair of columns, which triggered the previouslyPeter Eisentraut
mentioned bug.
2003-06-29Add missing PO files from last commit.Peter Eisentraut
2003-06-29Support expressions of the form 'scalar op ANY (array)' andTom Lane
'scalar op ALL (array)', where the operator is applied between the lefthand scalar and each element of the array. The operator must yield boolean; the result of the construct is the OR or AND of the per-element results, respectively. Original coding by Joe Conway, after an idea of Peter's. Rewritten by Tom to keep the implementation strictly separate from subqueries.
2003-06-28Merge PO file updates from 7.3 branch.Peter Eisentraut
2003-06-28Make information schema aware of arrays.Peter Eisentraut
The view element_types is currently not functional, awaiting some fixes in the planner (reported on -hackers).
2003-06-27Add is_superuser parameter reporting, soon to be used by psql.Tom Lane
2003-06-27Fix compile warnings.Tom Lane
2003-06-27First batch of object rename commands.Peter Eisentraut
2003-06-27Create real array comparison functions (that use the element datatype'sTom Lane
comparison functions), replacing the highly bogus bitwise array_eq. Create a btree index opclass for ANYARRAY --- it is now possible to create indexes on array columns. Arrange to cache the results of catalog lookups across multiple array operations, instead of repeating the lookups on every call. Add string_to_array and array_to_string functions. Remove singleton_array, array_accum, array_assign, and array_subscript functions, since these were for proof-of-concept and not intended to become supported functions. Minor adjustments to behavior in some corner cases with empty or zero-dimensional arrays. Joe Conway (with some editorializing by Tom Lane).
2003-06-26Add comment pointing out that XLByteToPrevSeg macro is not broken.Tom Lane
2003-06-25Back out array mega-patch.Bruce Momjian
Joe Conway
2003-06-25In ISO datestyle, never emit just HH:MM, always emit HH:MM:SS orTom Lane
HH:MM:SS.SSS... when there is a nonzero part-of-a-day field in an interval value. The seconds part used to be suppressed if zero, but there's no equivalent behavior for timestamp, and since we're modeling this format on timestamp it's probably wrong. Per complaint and patch from Larry Rosenman.
2003-06-25Don't generate 'zero' typeids in the output from gen_cross_product.Tom Lane
This is no longer necessary or appropriate since we don't use zero typeid as a wildcard anymore, and it fixes a nasty performance problem with functions with many parameters. Per recent example from Reuven Lerner.
2003-06-25 Fix up JOIN .. USING with domainsBruce Momjian
The attached fixes select_common_type() to support the below case: create table t1( c1 int); create domain dom_c1 int; create table t2(c1 dom_c1); select * from t1 join t2 using( c1 ); I didn't see a need for maintaining the domain as the preferred type. A simple getBaseType() call on all elements of the list seems to be enough. -- Rod Taylor <rbt@rbt.ca>
2003-06-25UPDATE ... SET <col> = DEFAULTBruce Momjian
Rod Taylor
2003-06-25Updated the pg_get_constraintdef() to use conbin. Update pg_dump to useBruce Momjian
pg_get_constraintdef() for >= 70400. Rod Taylor <rbt@rbt.ca>
2003-06-25Includes:Bruce Momjian
- LIKE <subtable> [ INCLUDING DEFAULTS | EXCLUDING DEFAULTS ] - Quick cleanup of analyze.c function prototypes. - New non-reserved keywords (INCLUDING, EXCLUDING, DEFAULTS), SQL 200X Opted not to extend for check constraints at this time. As per the definition that it's user defined columns, OIDs are NOT inherited. Doc and Source patches attached. -- Rod Taylor <rbt@rbt.ca>

This patch should hopefully fix both kerberos 4 and 5. Kurt Roeckx
2003-06-25Here's a small patch to pg_hba.conf.sample that explains the use of CIDRBruce Momjian
addresses. Andrew Dunstan

Here's a patch which also contains some more noncritical changes to tqual.c: . make code more readable by introducing local variables for xvac . no longer two separate branches for aborted and crashed. The actions were the same in all cases. Manfred Koizar
2003-06-24In an attempt to simplify my life I'm submitting this patch thatBruce Momjian
restructures the deferred trigger queue. The fundamental change is to put all the static variables to hold the deferred triggers in a single structure. Alvaro Herrera

2003-06-24Prevent compiler warning from sprintf in recent ipv6 patch.Bruce Momjian
2003-06-24 Add ipv6 address parsing support to 'inet' and 'cidr' data types.Bruce Momjian
Regression tests for IPv6 operations added. Documentation updated to document IPv6 bits. Stop treating IPv4 as an "unsigned int" and IPv6 as an array of characters. Instead, always use the array of characters so we can have one function fits all. This makes bitncmp(), addressOK(), and several other functions "just work" on both address families. add family() function which returns integer 4 or 6 for IPv4 or IPv6. (See examples below) Note that to add this new function you will need to dump/initdb/reload or find the correct magic to add the function to the postgresql function catalogs. IPv4 addresses always sort before IPv6. On disk we use AF_INET for IPv4, and AF_INET+1 for IPv6 addresses. This prevents the need for a dump and reload, but lets IPv6 parsing work on machines without AF_INET6. To select all IPv4 addresses from a table: select * from foo where family(addr) = 4 ... Order by and other bits should all work. Michael Graff
2003-06-22Revise hash join and hash aggregation code to use the same datatype-Tom Lane
specific hash functions used by hash indexes, rather than the old not-datatype-aware ComputeHashFunc routine. This makes it safe to do hash joining on several datatypes that previously couldn't use hashing. The sets of datatypes that are hash indexable and hash joinable are now exactly the same, whereas before each had some that weren't in the other.
2003-06-20Fix for extended-query protocol: in event of error, backend was issuingTom Lane
a ReadyForQuery (Z message) immediately and then another one after the Sync message arrives. Suppress the first one to make it work per spec.
2003-06-19Disallow dollar sign in operator names, instead allow it as a non-firstTom Lane
character in identifiers. The first change eliminates the current need to put spaces around parameter references, as in "x<=$2". The second change improves compatibility with Oracle and some other RDBMSes. This was discussed and agreed to back in January, but did not get done.
2003-06-17Make FLOAT(p) measure the precision p in bits, not decimal digits, toTom Lane
match the SQL standard. Document FLOAT and FLOAT(p) notations in datatype.sgml. Per recent pghackers discussion.
2003-06-17More information schema views.Peter Eisentraut
2003-06-16Fix bugs in interval-to-time conversion: HAVE_INT64_TIMESTAMP case did notTom Lane
work at all, and neither case behaved sanely for negative intervals.
2003-06-16Allow GROUP BY, ORDER BY, DISTINCT targets to be unknown literals,Tom Lane
silently resolving them to type TEXT. This is comparable to what we do when faced with UNKNOWN in CASE, UNION, and other contexts. It gets rid of this and related annoyances: select distinct f1, '' from int4_tbl; ERROR: Unable to identify an ordering operator '<' for type unknown This was discussed many moons ago, but no one got round to fixing it.
2003-06-15Adjust nestloop-with-inner-indexscan plan generation so that we catchTom Lane
some cases of redundant clauses that were formerly not caught. We have to special-case this because the clauses involved never get attached to the same join restrictlist and so the existing logic does not notice that they are redundant.
2003-06-15Replace cryptic 'Unknown kind of return type' messages with somethingTom Lane
hopefully a little more useful.
