Submit news and announcements by Sunday at 3:00pm Pacific time. Please send English language ones to david@fetter.org, German language to pwn@pgug.de, Italian language to pwn@itpug.org. == Applied Patches == Peter Eisentraut committed: - Add ONLY support to LOCK and TRUNCATE. By default, these commands are now recursive. Note this incompatibility in the release notes. - In pgsql/src/backend/parser/gram.y, use qualified_name instead of relation_expr for commands that have no business with inheritance recursion: ALTER INDEX, ALTER SEQUENCE, ALTER TRIGGER, ALTER VIEW. They would just silently ignore the ONLY. ALTER TABLE has mixed behavior and cannot be dealt with this way because of the resulting shift/reduce conflicts. - In pgsql/doc/src/sgml/ref/select.sgml, add some minimal documentation that the SQL standard requires parentheses after ONLY. - In pgsql/src/tools/make_etags, remove useless (and insecure) temp file handling. - In pgsql/src/interfaces/ecpg/ecpglib/Makefile, misc.o depends on pg_config_paths.h when --enable-nls is used. - In pgsql/src/pl/tcl/pltcl.c, make error messages match backend style. - In pgsql/src/backend/catalog/information_schema.sql, make the columns is_insertable_into and is_updatable behave uniformly correctly. They are supposed to examine which kinds of rules are present, which they did in some of the info schema views but not in others. - In pgsql/src/tools/make_etags, avoid version-control system directories when creating TAGS. Besides being wasteful, this can collide with repostory metadata on case-insensitive file sytems. - In pgsql/src/nls-global.mk, make .pot files depend on the makefiles, so that they are updated when the file or trigger function lists are changed. - In pgsql/src/interfaces/ecpg/test/Makefile, build needed things in src/test/regress/ first. And some build rules normalization. - NLS cleanup in ecpglib Replace leftover instances of _() by ecpg_gettext(), the latter being the correct way to refer to the library's message catalog, instead of the one of the program using the library. Drop NLS support for ecpg_log(), which is a debugging instrument similar to elog() in the backend. We cannot support NLS in the ecpg compatlib, because that requires ecpg_gettext, which is in ecpglib, which is not a dependency of compatlib. It doesn't seem worthwhile to worry about this, since the only translatable string is "out of memory", and gettext probably won't be able to do much without memory either. Adjust messages to project style. - In pgsql/src/pl/tcl/nls.mk, remove unneeded GETTEXT_TRIGGERS. - Cleanup pass over PL/Python NLS. Add translation support to PLy_elog and PLy_exception_set, and clarify some error messages. - In pgsql/src/bin/pg_ctl/pg_ctl.c, remove period from primary error message. - Wordsmithing in pgsql/src/interfaces/ecpg/ecpglib/error.c. - plpython_error.out is for Python 2.4, plpython_error_3.out is for Python 2.5, as it was previously. - In pgsql/src/pl/plpython/expected/plpython_error_1.out, manual attempt to update this file. Tom Lane committed: - In pgsql/src/backend/executor/nodeBitmapHeapscan.c, tweak order of operations in BitmapHeapNext() to avoid the case of prefetching the same page we are nanoseconds away from reading for real. There should be something left to do on the current page before we consider issuing a prefetch. - Fix a pg_dump output ordering problem introduced in 8.3 by the addition of array types for composite types. Although pg_dump understood it wasn't supposed to dump these array types as separate objects, it must include them in the dependency ordering analysis, and it was improperly assigning them the same relatively-high sort priority as regular types. This resulted in effectively moving composite types and tables up to that same high priority, which broke any ordering requirements that weren't explicitly enforced by dependencies. In particular user-defined operator classes, which should come out before tables, failed to do so. Per report from Brendan Jurd. In passing, also fix an ill-considered decision to give text search objects the same sort priority as functions and operators --- the sort result looks a lot nicer if different object types are kept separate. The recent foreign-data patch had copied that decision, making the sort ordering even messier :-( Alvaro Herrera committed: - Simplify the writing of amoptions routines by introducing a convenience fillRelOptions routine that stores the parsed values in the struct using a table-based approach. Per Tom suggestion. Also remove the "continue" in HANDLE_*_RELOPTION macros, which were useless and in spirit they were assuming too much of how the macros were going to be used. (Note that these macros are now unused, but the intention is to introduce some usage in a future autovacuum patch, which is why they weren't completely removed.) Also, do not call the string validation routine when not validating. It seems less error-prone this way, per commentary on the amoptions SGML docs. - Backpatch to 7.4 the part of 1.84 (from the 8.0 timeline) that wasn't already patched, viz. str_numth(). The rest of that patch was already applied as part of 1.69.2.1. Per report and patch from Andreas 'ads' Scherbaum. Bruce Momjian committed: - In pgsql/doc/src/sgml/backup.sgml, document how pglesslog can be used to reduce the storage requirements of PITR. - Renable threading build for Solaris 2.5, per report from Andrew Chernow. - Check nsl library for gethostbyname_r() on all platforms (HP-UX uses it too). - In pgsql/src/port/thread.c, remove empty #ifdef block. - Make 'find' syntax consistent; add .git exclusion to make_ctags. - In pgsql/doc/src/sgml/wal.sgml, add documentation mention that full page writes have to be enabled for full pages to be restored during recovery. Per private report from Michael Renner - In pgsql/GNUmakefile.in, modify distdir rule to skip .git directory. Magnus Hagander committed: - In pgsql/src/interfaces/libpq/fe-auth.c, remove special-handling of usernames with Kerberos authentication. We will now always use the system username as the default, and not try to pick it up from the kerberos ticket. This fixes the spurious error messages that show up on kerberos-enabled builds when not actually using kerberos, and puts it in line with how other authentication methods work. - In pgsql/src/bin/pg_dump/pg_backup_archiver.c, throw an error when using -C and -1 at the same time in pg_restore. It's not possible to do CREATE DATABASE inside a transaction, so previously we just got a server error instead. Backpatch to 8.2, which is where the -1 feature appeared. Heikki Linnakangas committed: - In pgsql/src/pl/plpgsql/src/pl_exec.c, remove broken Assertions that failed if a statement executed in PL/pgSQL is rewritten into another kind of statement, for example if an INSERT is rewritten into an UPDATE. Back-patch to 8.3 and 8.2. For HEAD, Tom suggested inventing a new SPI_OK_REWRITTEN return code, but that's not a backportable solution. I'll do that as a separate patch, this patch will do as a stopgap measure for HEAD too in the meanwhile. - In pgsql/doc/src/sgml/func.sgml, change explanation of pg_switch_xlog()'s return value to match code. - Add vacuum_freeze_table_age GUC option, to control when VACUUM should ignore the visibility map and scan the whole table, to advance relfrozenxid. Teodor Sigaev committed: - In pgsql/src/backend/tsearch/wparser_def.c, fix generation too long headline with ShortWords. Per http://archives.postgresql.org/pgsql-hackers/2008-09/msg01088.php - Fix URL generation in headline. Only tag lexeme will be replaced by space. Per http://archives.postgresql.org/pgsql-bugs/2008-12/msg00013.php - In pgsql/contrib/tsearch2/expected/tsearch2.out, sync output of tsearch2 regression test. - In pgsql/contrib/tsearch2/rank.c, fix uninitialized variables in get_covers. Neil Conway committed: - In pgsql/doc/src/sgml/ref/create_user_mapping.sgml, fix typo. - In pgsql/doc/src/sgml/ref/create_server.sgml, fix an ungrammatical statement. == Rejected Patches (for now) == No one was disappointed this week :-) == Pending Patches == Koichi Suzuki sent in another revision of the PITR improvement patch.
