== Postgres Weekly News - February 24 2008 ==

FOSDEM was a smash hit for Postgres.  The talks were frequently
standing room only; the people staffing the booth were enthusiastic
and knowledgeable, and the donations were sky high.  Kudos to all who
made it happen.

The EU PostgreSQL User Group now has a board of directors: Jean-Paul
Agudo of France, Gabriele Bartolini of Italy, Magnus Hagander of
Sweden and Andreas Scherbaum of Germany.  Congratulations to all!

== Applied Patches ==

Peter Eisentraut committed:

- In pgsql/src/backend/tsearch/Makefile, observe errors.

- Added --htmldir option to pg_config, equivalent to the new configure

- Refactor backend makefiles to remove lots of duplicate code.

- In pgsql/src/backend/access/common/Makefile, remove another target I
  forgot during the refactoring.

- Remove pgsql/src/backend/port/sunos4.  This subdirectory has been
  unused, dead, and broken for 10 years.

- More refactoring, so that the SUBSYS.o rules are now all in one

- Backport fixed AC_FUNC_FSEEKO

Bruce Momjian committed:

- autoconf 2.61's AC_FUNC_FSEEKO reports success/failure differently,
  so reorganize code for NetBSD/BSDi port/fseeko.c usage, and make
  code more modular.

- Put fseeko check back in old location, in hopes of silencing build

- Put back code modularization of fseeko() configure checks.

Tom Lane committed:

- Remove unnecessary opening of other relation in RI_FKey_keyequal_upd_pk
  and RI_FKey_keyequal_upd_fk, as well as no-longer-needed calls of
  ri_BuildQueryKeyFull.  Aside from saving a few cycles, this avoids
  needless deadlock risks when an update is not changing the columns
  that participate in an RI constraint.  Per a gripe from Alexey
  Nalbat.  Back-patch to 8.3.  Earlier releases did have a need to
  open the other relation due to the way in which they retrieved
  information about the RI constraint, so this problem unfortunately
  can't easily be improved pre-8.3.  Tom Lane and Stephan Szabo

- In pgsql/src/backend/catalog/catalog.c, put a CHECK_FOR_INTERRUPTS
  call into the loops that try to find a unique new OID or new
  relfilenode.  If the existing OIDs are sufficiently densely
  populated, this could take a long time (perhaps even be an infinite
  loop), so it seems wise to allow the system to respond to a cancel
  interrupt here.  Per a gripe from Jacky Leng.  Backpatch as far as
  8.1.  Older versions just fail on OID collision, instead of looping.

- In pgsql/src/bin/pg_ctl/pg_ctl.c, fix mistakes in pg_ctl's code for
  "start -w" that tries to cope with non-default settings for the
  postmaster's port number.  The code to parse command line options
  and postgresql.conf entries wasn't quite right about whitespace or
  quotes, and it was coded in a not-very-readable way too.  Per bug
  #3969 from Itagaki Takahiro, though this is more extensive than his
  proposed patch (which fixed only the whitespace problem).  This code
  has been broken since it was put in in 8.0, so patch all the way

- In pgsql/src/test/regress/pg_regress.c, make pg_regress -V
  consistent with the corresponding code in other programs: use puts
  with a compile-time-constant string.

- Rename miscadmin.h's PG_VERSIONSTR macro to PG_BACKEND_VERSIONSTR to
  make it a bit clearer what it is, and get rid of duplicate
  definitions in initdb and pg_ctl.

- Change the declaration of struct varlena so that the length word is
  represented as "char ...[4]" not "int32".  Since the length word is
  never supposed to be accessed via this struct member anyway, this
  won't break any existing code that is following the rules.  The
  advantage is that C compilers will no longer assume that a pointer
  to struct varlena is word-aligned, which prevents incorrect
  optimizations in TOAST-pointer access and perhaps other places.  gcc
  doesn't seem to do this (at least not at -O2), but the problem is
  demonstrable on some other compilers.  I changed struct inet as
  well, but didn't bother to touch a lot of other struct definitions
  in which it wouldn't make any difference because there were other
  fields forcing int alignment anyway.  Hopefully none of those struct
  definitions are used for accessing unaligned Datums.

- In pgsql/src/backend/utils/misc/help_config.c, avoid trying to print
  a NULL char pointer in --describe-config.  On some platforms this
  works, but on some it crashes.  Zdenek Kotala

- Use our own getopt() and getopt_long() on Solaris, because that
  platform's versions don't handle long options the way we want.  Per
  Zdenek Kotala.

Magnus Hagander committed:

- In pgsql/src/tools/msvc/, unbreak MSVC build after recent
  addition of HTMLDIR.

- In pgsql/src/timezone/strftime.c, fix function prototype to silence
  compiler warnings.

- In pgsql/src/tools/msvc/, un-break msvc port yet again (it
  started pulling in the Darwin port files, which obviously didn't

Alvaro Herrera committed:

- In pgsql/src/backend/postmaster/autovacuum.c, change error message
  to be able to differentiate the two cases.  Per suggestion from
  Jaime Casanova.

- Improve error messages emitted when VACUUM and ANALYZE skip a table.
  Per gripe from Clodoaldo Pinto Neto.

== Rejected Patches (for now) ==

No one was disappointed this week :-)

== Pending Patches ==

Gevik Babakhani sent in a patch to fix MSVC compilation on MSVC.

Tatsuhito Kasahara sent in two revisions of a patch intended to change
pgstatindex.c and pgstattuple.sql, where some variables are defined
with int type, to a larger numeric type, which in turn allows for
larger tables.

Davd Page sent in a patch which fixes initdb failures on Windows
stemming from recent security-related changes to that platform.

Zdenek Kotala sent in three revisions of a patch intended to fix
non-portable getopt() code.

Neil Conway sent in a patch to fix some memory leaks in the
implementaiton of set-returning functions.

Peter Eisentraut sent in a patch links the backend in one piece
instead of many files.

Robert Lor sent in a patch to change the DTrace probes from the
DTRACE_PROBEn implementation to the header macro implementation so
that the probes can be used on OSs other than Solaris including OSX

Heikki Linnakangas sent in an optimization for CopyReadLineText which
should speed up COPY operations in many common cases.
