Warm Standby: If setting up Warm Standby confused you before, give it
a try with 8.4; it's now user-friendly.

== PostgreSQL Tip of the Week ==

Until 8.4's Common Table Expressions and 8.5's SQL/MED come out, you
can use the "tablefunc" contrib module includes functions for

respectively.

== 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.
