== PostgreSQL Weekly News - August 06 2006 ==

Pervasive announced the end of their PostgreSQL support last week.
We're sorry to lose a member of our corporate community who have been
so supportive.  Commercial support for PostgreSQL is available from
several other companies.  Pervasive will be donating their
documentation and PR collateral to the PostgreSQL community.

The Gorda Project has created a preliminary PostgreSQL implementation
of their database replication.

== Applied Patches == 

Michael Meskes committed:

- His patches to ECPG that will support regression tests.

- Implemented EXEC SQL UNDEF.

- Regression test patch by Joachim Wieland.

Tatsuo Ishii committed:

- ITAGAKI Takahiro's fix for an overflow bug in contrib/pgbench.

Bruce Momjian committed:

- Joshua Drake's patch which updates the docs on Maintenance and
  External Projects.

- Greg Sabino Mullane's patch which adds regex matching and multiple
  -n and -t options to pg_dump.

- Martin Pitt's patch which causes pg_dump not to restore TABLE DATA
  objects if the corresponding TABLE object failed to be created.

- A patch which lets people log the parameters when executing prepared
  statements.  And there was much rejoicing.

Andrew Dunstan committed:

- a patch that causes pg_regress to fall back on testing with the
  canonical results file if an alternative test is specified but none
  succeeds.

Joe Conway committed:

- his multiple-tuple INSERT, which is now working faster in less RAM
  than a certain Swedish company's.

Tom Lane committed:

- a HINT per suggestion from Michael Glaesemann for cases where the
  new multiple-tuple INSERT fails.

- Andreas Seltenreich's patch which fixes stats collection for GIN
  indexes.

- Michael Fuhr's patch which causes g_trigtuple and tg_newtuple to be
  cleared to NULL in AFTER STATEMENT triggers.

- Gavin Sherry's patch which adds regression tests for the new VALUES
  features including multiple-tuple INSERTs.

- Joachim Wieland's basic regression tests of GUC behavior.

- A patch which teaches the optimizer to simplify BooleanTest nodes
  that have constant input.

- A patch to domain_in() which fixes a bug that Darcy Buskermolen
  found.

- A patch per example from Martin Lesser which makes constraint
  exclusion work better by extending relation_excluded_by_constraints()
  to check for mutually exclusive WHERE clauses.  A rename and/or new
  GUC variable may be in the works.

- Another patch per example from Martin Lesser which teaches
  predicate_refuted_by() how to do proofs involving NOT-clauses.  This
  helps with the IS NOT TRUE clauses which the rule rewriter tends to
  insert.

- A fix to inheritance_planner() to delete dummy subplans from its
  Append plan list, when some of the child rels have been excluded by
  constraint exclusion.  This doesn't save a huge amount of time but
  it'll save some, and it makes the EXPLAIN output look saner.  This
  parallels the equivalent change in set_append_rel_pathlist()

- Simon Riggs's patch that helps do archive timeouts and one which
  allows people to force the WAL file to be written out along with
  some miscellanea discussed at the conference.  Also ways to have
  restartable recovery.

Neil Conway committed:

- Michael Fuhr's patch which fixes the pgcrypto documentation.
