Bruce Momjian committed:

- Modify pg_upgrade to set/restore all environment variables related
  to collation/encoding to match English when reading controldata.
  This now matches the English variable setting used by pg_regress.c.
  Backpatch to 9.0.X.

- Doc fixes: 1. Remove excessive table cells.  2. Moving function
  parameters into function tags rather than having them being
  considered separate.  3. Add return type column on XML2 contrib
  module functions list and removing return types from function.  4.
  Add table header to XML2 contrib parameter table.  Thom Brown.
  Backpatch to 9.0.X.

- In pgsql/doc/src/sgml/backup.sgml, re-add documentation for Win32
  copy syntax for archive_command.  Backpatch to 9.0.X.

- In pgsql/doc/src/sgml/backup.sgml, don't try aligning comments for
  new archive_command Win32 doc example; it doesn't work.  Backpatch
  to 9.0.X.

Peter Eisentraut committed:

- In pgsql/doc/src/sgml/syntax.sgml, clarify that surrogate pairs are
  not encoded in UTF-8 directly.

- Add tip about building plpython 2 and 3.  Fix link to Python docs.

Tom Lane committed:

- In pgsql/doc/src/sgml/installation.sgml, remove obsolete claim that
  gzip is needed while installing PG's documentation.  It isn't, now
  that we ship the docs as loose files rather than a sub-tarball.
  Also adjust the wording in a couple of places to make the lists of
  required software read more consistently.

Michael Meskes committed:

- Cursor names in the backend are not case-sensitve.  This change
  makes sure that ecpg also does not regard cursor names as
  case-sensitive.  Thanks to Zoltan Boszormenyi for the patch.

Heikki Linnakangas committed:

- Introduce latches.  A latch is a boolean variable, with the
  capability to wait until it is set.  Latches can be used to reliably
  wait until a signal arrives, which is hard otherwise because signals
  don't interrupt select() on some platforms, and even when they do,
  there's race conditions.  On Unix, latches use the so called
  self-pipe trick under the covers to implement the sleep until the
  latch is set, without race conditions.  On Windows, Windows events
  are used.  Use the new latch abstraction to sleep in walsender, so
  that as soon as a transaction finishes, walsender is woken up to
  immediately send the WAL to the standby.  This reduces the latency
  between master and standby, which is good.  Preliminary work by
  Fujii Masao.  The latch implementation is by me, with helpful
  comments from many people.

- In pgsql/src/backend/port/unix_latch.c, add missing #includes,
  needed on some platforms.  This should make the unixware buildfarm
  animals happy again.

Joe Conway committed:

- SERIALIZABLE transactions are actually implemented beneath the
  covers with transaction snapshots, i.e. a snapshot registered at the
  beginning of a transaction.  Change variable naming and comments to
  reflect this reality in preparation for a future, truly serializable
  mode, e.g. Serializable Snapshot Isolation (SSI).  For the moment
  transaction snapshots are still used to implement SERIALIZABLE, but
  hopefully not for too much longer.  Patch by Kevin Grittner and Dan
  Ports with review and some minor wording changes by me.

Robert Haas committed:

- In pgsql/doc/src/sgml/catalogs.sgml, link from pg_shadow docs to
  pg_authid docs.  Per discussion with Josh Kupershmidt.
