Applied Patches
Peter Eisentraut committed:
- Some documentation cleanup for the addition of the KOI8U encoding. Change all (remaining) mentions of KOI8 to the new canonical form KOI8R. Add information about the available conversions for KOI8U.
- Refer to tables by id, not by "the following table", because tables are in theory floating elements.
- In pgsql/src/backend/catalog/sql_features.txt, update SQL conformance entries for window functions functionality
- In pgsql/src/tools/editors/emacs.samples, add some instructions on how to customize emacs for working on the SGML sources.
- Add documentation string for LDFLAGS_SL in configure --help output.
- In pgsql/src/tools/editors/emacs.samples, fix sgml-mode example. Thanks, Andrew Dunstan.
- In pgsql/src/bin/pg_dump/pg_dump.c, convert some messages to use ngettext(). Author: Euler Taveira de Oliveira.
Tom Lane committed:
- In pgsql/src/interfaces/libpq/fe-connect.c, make pwdfMatchesString() a little more careful about matching * fields.
- Fix bug #4814 (wrong subscript in consistent-function call), and add some minimal regression test coverage for matchPartialInPendingList().
- Fix LIKE's special-case code for % followed by _. I'm not entirely sure that this case is worth a special code path, but a special code path that gets the boundary condition wrong is definitely no good. Per bug #4821 from Andrew Gierth. In passing, clean up some minor code formatting issues (excess parentheses and blank lines in odd places). Back-patch to 8.3, where the bug was introduced.
- Use more-portable coding for the check on handing out the last available relopt_kind value in add_reloption_kind(). Per Zdenek Kotala.
Heikki Linnakangas committed:
- In pgsql/src/backend/commands/analyze.c, update relpages and reltuples estimates in stand-alone ANALYZE, even if there's no analyzable attributes or indexes. We also used to report 0 live and dead tuples for such tables, which messed with autovacuum threshold calculations. This fixes bug #4812 reported by George Su. Backpatch back to 8.1.
- In pgsql/src/backend/commands/tablecmds.c, silence a gcc compiler warning about non-literal format string with no args when compiling with -Wformat-security. Fujii Masao.
Michael Meskes committed:
- Removed some unneeded variables and comparisons.
- More variables gcc moans about.
- Removed unsigned/signed mismatches.
- Removed comparison of unsigned expression < 0.
Teodor Sigaev committed:
- In pgsql/src/backend/utils/adt/tsvector.c, re-sort tsvector's lexemes in tsvectorrecv instead of emitting an error. Basically, it's needed to support binary dump from 8.3 because the ordering rule was changed. Per discussion with Bruce Momjian.
