Please send English language ones to [EMAIL PROTECTED], German language to [EMAIL PROTECTED], Italian language to [EMAIL PROTECTED] == Applied Patches == Alvaro Herrera committed: - Add generate_subscripts, a series-generation function which generates an array's subscripts. Pavel Stehule, some editorialization by me. - Bump the catversion for the previous patch. - Fix volatility marking for the generate_series and generate_subscripts families of functions. - Remove typename from A_Const. Brendan Jurd, minor editorialization by me. - Fix REASSIGN OWNED so that it works on procedural languages too. The capability for changing language owners is new in 8.3, so that's how far back this needs to be backpatched. Per bug #4132 by Kirill Simonov. - In pgsql/doc/src/sgml/ref/alter_role.sgml, add example showing how to remove a password from a role. Andreas Scherbaum. Tom Lane committed: - Fix broken configure test for libxslt: it was probing for xsltLibxmlVersion, which is a global variable not a function, and so the probe failed on machines where the linker makes a distinction (cf. Red Hat bug #444317). Probe for an actual function instead. - Increase the statement_timeout value used in the prepared_xacts regression test. We have seen some buildfarm failures that seem to be due to this limit being unexpectedly exceeded when the machine is under load. - Some minor further cleanup around A_Const. Don't attach a typecast in makeFloatConst, and avoid "manual" construction of A_Const nodes in grammar productions, in favor of using makeXXXConst subroutines. - In pgsql/src/backend/executor/nodeTidscan.c, fix nodeTidscan.c to not trigger an error if the block number portion of a user-supplied TID is out of range for the relation. This is needed to preserve compatibility with our pre-8.3 behavior, and it is sensible anyway since if the query were implemented by brute force rather than optimized into a TidScan, the behavior for a non-existent TID would be zero rows out, never an error. Per gripe from Gurjeet Singh. - Make the minimum allowed value of work_mem be 64KB always, rather than having it vary with BLCKSZ as before. This agrees with what the documentation says, and avoids a regression test problem when BLCKSZ is larger than default. Per recent discussion. - Add SGT (Singapore time) to the default list of known timezone abbreviations. It doesn't conflict with any other abbreviation so there seems no reason not to include it. Per a recent gripe. - Remove the recently added USE_SEGMENTED_FILES option, and indeed remove all support for a nonsegmented mode from md.c. Per recent discussions, there doesn't seem to be much value in a "never segment" option as opposed to segmenting with a suitably large segment size. So instead provide a configure-time switch to set the desired segment size in units of gigabytes. While at it, expose a configure switch for BLCKSZ as well. Zdenek Kotala - In pgsql/src/include/pg_config.h.win32, sigh ... pg_config.h.win32 needs to define BLCKSZ and RELSEG_SIZE now. - Extend yesterday's patch making BLCKSZ and RELSEG_SIZE configurable to also let XLOG_BLCKSZ and XLOG_SEG_SIZE be set via configure. Per a proposal by Mark Wong, though I thought it better to call the switches after "wal" rather than "xlog". - Allow the planner's estimate of the fraction of a cursor's rows that will be retrieved to be controlled through a GUC variable. Robert Hell - In pgsql/doc/src/sgml/ref/psql-ref.sgml, update documentation for psql relation-size-in-\dt+ patch. - Support RETURN QUERY EXECUTE in plpgsql. Pavel Stehule. - Fix plpython to not get totally confused by OUT arguments. (It still doesn't support multiple OUT arguments, though.) Hannu Krosing - In pgsql/src/backend/utils/adt/ruleutils.c, the 8.2 patch that added support for an alias on the target table of UPDATE/DELETE forgot to teach ruleutils.c to display the alias. Per bug #4141 from Mathias Seiler. - Use new cstring/text conversion functions in some additional places. These changes assume that the varchar and xml data types are represented the same as text. (I did not, however, accept the portions of the proposed patch that wanted to assume bytea is the same as text --- tgl.) Brendan Jurd - Add pg_conf_load_time() function to report when the Postgres configuration files were last loaded. George Gensure - Add timestamp and timestamptz versions of generate_series(). Hitoshi Harada Bruce Momjian committed: - Update TODO comment for 8.4: '#A hyphen, "-", marks changes that will appear in the upcoming 8.4 release.#' Peter Eisentraut committed: - In psql, one-letter backslash commands now need a space before the first argument. This has been the only documented and encouraged syntax for a long time, and with extension facilities such as aliases being proposed, it is a good time to clean up the legacy syntax a bit. Bernd Helmle. - In pgsql/src/backend/utils/Gen_fmgrtab.sh, make the AWK default value also take effect if $AWK is an empty string. Heikki Linnakangas committed: - In pgsql/src/bin/psql/describe.c, show relation size in verbose (e.g. \d+) output. Dickson S. Guedes. Andrew Dunstan committed: - Provide for MSVC config equivalents of recently added configure options. Remove any hardcoding of those options. Along the way, reorder the expression used to calculate RELSEG_SIZE to make it slightly clearer. For now wal_segsize is only allowed to have a value of 1 on Windows - we can relax that when we get full large file support in the backend. - Disable statement timeouts while making or restoring dumps. Joshua Drake. - In pgsql/src/bin/pg_dump/pg_backup_archiver.c, place statement timeout more appropriately, per gripe from Tom Lane. - In pgsql/src/bin/pg_dump/pg_backup_archiver.c, add ; missing due to my carelessness. - Show enum values in psql's \dT+. David Fetter. - Display ACLS using multiple lines for psql's \z. Brendan Jurd. - In pgsql/doc/src/sgml/ref/psql-ref.sgml, document extra information provided by psql's \dT+. == Rejected Patches (for now) == Sergey Zubkovsky's patch to patch pg_total_relation_size() for Windows. Magnus Hagander had already committed a similar patch. == Pending Patches == Bruce Momjian sent in another revision of Bryce Nesbitt's patch to wrap psql output at window width. Heikki Linnakangas sent in a WIP patch to implement map forks. George Gensure sent in two revisions of a patch to add pg_conf_load_time(). Merlin Moncure sent in another revision of the libpq object hooks patch. Magnus Hagander sent in a patch to add functions which make it possible to implement pg_stat_activity as a SRF. Andreas (ads) Scherbaum sent in another revision of his patch to implement "CREATE OR REPLACE LANGUAGE." Dave Page sent in three revisions of a patch which implements pg_get_keywords(). Tom Lane sent in a revised version of ITAGAKI Takahiro's patch to sort writes during checkpoints. ---------------------------(end of broadcast)--------------------------- -To unsubscribe from this list, send an email to: [EMAIL PROTECTED]
