< * -Make postmater and postgres options distinct so the postmaster -o < option is no longer needed < * -Allow pooled connections to list all prepared statements < < This would allow an application inheriting a pooled connection to know < the statements prepared in the current session. < < * -Re-enable the GUC full_page_writes in 8.2 when reliability issues have < been addressed < o -Add "include file" functionality in postgresql.conf < o -Allow per-database permissions to be set via GRANT < < Allow database connection checks based on GRANT rules in < addition to the existing access checks in pg_hba.conf. < < o -Issue a warning if a change-on-restart-only postgresql.conf value > o Issue a warning if a change-on-restart-only postgresql.conf value < o -Automatically force archiving of partially-filled WAL files when < pg_stop_backup() is called or the server is stopped < o -Add reporting of the current WAL file and offset, perhaps as < part of partial log file archiving < * -Allow server logs to be remotely read and removed using SQL commands < * -Allow protocol-level BIND parameter values to be logged < * -Zero umasked bits in conversion from INET cast to CIDR < * -Prevent INET cast to CIDR from dropping netmask, SELECT '1.1.1.1'::inet::cidr < * -Allow INET + INT8 to increment the host part of the address or < throw an error on overflow < * -Add 'tid != tid ' operator for use in corruption recovery < o -Allow customization of the known set of TZ names (generalize the < present australian_timezones hack) < o -Allow timezone names in SQL strings, '2006-05-24 21:11 < Americas/New_York'::timestamptz < o -Add support for day-time syntax, INTERVAL '1 2:03:04' DAY TO < SECOND < o -Allow NULLs in arrays < * -Add transaction_timestamp(), statement_timestamp(), clock_timestamp() < functionality < < Current CURRENT_TIMESTAMP returns the start time of the current < transaction, and gettimeofday() returns the wallclock time. This will < make time reporting more consistent and will allow reporting of < the statement start time. < < * -Allow to_char() to print localized month names < * -Add sleep() function, remove from regress.c < * -Allow user-defined functions retuning a domain value to enforce domain < constraints < * -Allow TRUNCATE ... CASCADE/RESTRICT < < This is like DELETE CASCADE, but truncates. < < * -Add COMMENT ON for all cluster global objects (roles, databases < and tablespaces) < * -Make row-wise comparisons work per SQL spec < < Right now, '(a, b) < (1, 2)' is processed as 'a < 1 and b < 2', but < the SQL standard requires it to be processed as a column-by-column < comparison, so the proper comparison is '(a < 1) OR (a = 1 AND b < 2)'. < < * -Enable escape_string_warning and standard_conforming_strings > * Enable standard_conforming_strings < o -Add ON COMMIT capability to CREATE TABLE AS ... SELECT < o -Allow an alias to be provided for the target table in < UPDATE/DELETE (Neil) < o -Allow UPDATE tab SET ROW (col, ...) = (val, ...) for updating < multiple columns < o -Add ALTER TABLE tab INHERIT / NO INHERIT parent < o -Have COPY return the number of rows loaded/unloaded? < o -Allow COPY (SELECT ...) TO 'filename' < < o -Allow pooled connections to list all open WITH HOLD cursors < < Because WITH HOLD cursors exist outside transactions, this allows < them to be listed so they can be closed. < < o -Allow INSERT INTO tab (col1, ..) VALUES (val1, ..), (val2, ..) < o -Allow INSERT/UPDATE ... RETURNING new.col or old.col < o -Allow PL/python to return composite types and result sets < < * -Have initdb set the input DateStyle (MDY or DMY) based on locale < o -Improve psql's handling of multi-line statements < < Currently, while \e saves a single statement as one entry, interactive < statements are saved one line at a time. Ideally all statements < would be saved like \e does. < < o -Allow multi-line column values to align in the proper columns < < If the second output column value is 'a\nb', the 'b' should appear < in the second display column, rather than the first column as it < does now. < < o -Display IN, INOUT, and OUT parameters in \df < o -Allow pg_dump to use multiple -t and -n switches, exclusion < ability, and regular expression object matching < o -Update pg_dump and psql to use the new COPY libpq API (Christopher) < o -Add a function to support Parse/DescribeStatement capability < * -Add fillfactor to control reserved free space during index creation < * -Add system view to show free space map contents < * -Allow installing to directories containing spaces < < This is possible if proper quoting is added to the makefiles for the < install targets. Because PostgreSQL supports relocatable installs, it < is already possible to install into a directory that doesn't contain < spaces and then copy the install to a directory with spaces. < < * -%Clean up compiler warnings (especially with gcc version 4) < * -Remove BeOS and QNX-specific code < o -Port contrib/xml2
2006-09-19Document how to use psql's --single-transaction option to rollback restoringNeil Conway

2006-09-18Add built-in userlock manipulation functions to replace the formerTom Lane
contrib functionality. Along the way, remove the USER_LOCKS configuration symbol, since it no longer makes any sense to try to compile that out. No user documentation yet ... mmoncure has promised to write some. Thanks to Abhijit Menon-Sen for creating a first draft to work from.

2006-09-17Change ANALYZE to take ShareUpdateExclusiveLock not AccessShareLock onTom Lane
the table being analyzed. This prevents two ANALYZEs from running concurrently on the same table and possibly suffering concurrent-update failures while trying to store their results into pg_statistic. The downside is that a database-wide ANALYZE executed within a transaction block will hold ShareUpdateExclusiveLock on many tables simultaneously, which could lead to concurrency issues or even deadlock against another such ANALYZE. However, this seems a corner case of less importance than getting unexpected errors from a foreground ANALYZE when autovacuum elects to analyze the same table concurrently. Per discussion.
2006-09-16Update TODO for short header versions:Bruce Momjian
< o Reorder physical storage order to reduce padding? < < This involves having the user-specified order of columns < be different from the physical order. SELECT * would < need to reorder the physical values to match the < user-specified ordering. < < o Store disk pages with no alignment/padding? < < This necessitates adding CPU-required padding when moving < rows from disk to memory. < < One idea is to store the header in network byte order (high bits < first), and read the high bits to determine the header length. < http://archives.postgresql.org/pgsql-hackers/2006-09/msg00848.php > One idea is to create zero-or-one-byte-header versions > of varlena data types. In involves setting the high-bit and > 0-127 length in the single-byte header, or clear the high bit > and store the 7-bit ASCII value in the rest of the byte. > The small-header versions have no alignment requirements. > http://archives.postgresql.org/pgsql-hackers/2006-09/msg01372.php
2006-09-16Rename the recently-added pg_timezonenames view to pg_timezone_abbrevs,Tom Lane
and create a new view pg_timezone_names that provides information about the zones known in the 'zic' database. Magnus Hagander, with some additional work by Tom Lane.
2006-09-16Rename xml_valid() to xml_is_well_formed(), but provide a temporaryTom Lane
alias with the old name for backwards compatibility. Per discussion, the old name is actively wrong because validity and well-formedness have different meanings in XML.

Simon Riggs
2006-09-14Add a couple of information functions to support direct checks on whetherTom Lane
a schema is our own temp schema or another backend's temp schema, and use these in place of some former kluges in information_schema. Per my proposal of yesterday.

2006-09-10Remove unhelpful/misleading advice about how to use SPI_saveplan().Tom Lane
Per gripe from Jack Orenstein.
2006-09-10Add missing documentation for new anyarray-overlap operator.Tom Lane
2006-09-10Rename contrib contains/contained-by operators to @> and <@, per discussion.Tom Lane
2006-09-10Rename contains/contained-by operators to @> and <@, per discussion thatTom Lane
agreed these symbols are less easily confused. I made new pg_operator entries (with new OIDs) for the old names, so as to provide backward compatibility while making it pretty easy to remove the old names in some future release cycle. This commit only touches the core datatypes, contrib will be fixed separately.
2006-09-09Remove reference to contrib/mac, which isn't there anymore.Tom Lane
2006-09-08Tweak the behavior of log_duration as proposed by Guillaume Smet: ratherTom Lane
than being equivalent to setting log_min_duration_statement to zero, this option now forces logging of all query durations, but doesn't force logging of query text. Also, add duration logging coverage for fastpath function calls.
