== Applied Patches ==

Jeff Davis pushed:

- Add buffer_std flag to MarkBufferDirtyHint().  MarkBufferDirtyHint()
  writes WAL, and should know if it's got a standard buffer or not.
  Currently, the only callers where buffer_std is false are related to
  the FSM.  In passing, rename XLOG_HINT to XLOG_FPI, which is more
  descriptive.  Back-patch to 9.3.

Peter Eisentraut pushed:

- psql: Re-allow -1 together with -c or -l

- initdb: Add blank line before output about checksums.  This
  maintains the logical grouping of the output better.

- Further update CREATE FUNCTION documentation about argument names.
  More languages than SQL and PL/pgSQL actually support parameter

- Clarify terminology standalone backend vs. single-user mode.  Most
  of the documentation uses "single-user mode", so use that in the
  code as well.  Adjust the documentation to match the new error
  message wording.  Also add a documentation index entry for
  "single-user mode".  Based-on-patch-by: Jeff Janes.

- doc: Fix date in EPUB manifest.  If there is no  element, the
  publication date for the EPUB manifest is taken from the copyright
  year.  But something like "1996-2013" is not a legal date
  specification.  So the EPUB output currently fails epubcheck.  Put
  in a separate  element with the current year.  Put it in
  legal.sgml, because copyright.pl already instructs to update that
  manually, so it hopefully won't be missed.

Simon Riggs pushed:

- Fix docs on lock level for ALTER TABLE VALIDATE.  ALTER TABLE ..
  VALIDATE CONSTRAINT previously gave incorrect details about lock
  levels and therefore incomplete reasons to use the option.  Initial
  bug report and fix from Marko Tiikkaja Reworded by me to include
  comments by Kevin Grittner

- Ensure no xid gaps during Hot Standby startup.  In some cases with
  higher numbers of subtransactions it was possible for us to
  incorrectly initialize subtrans leading to complaints of missing
  pages.  Bug report by Sergey Konoplev.  Analysis and fix by Andres

Kevin Grittner pushed:

- Fix the create_index regression test for Danish collation.  In
  Danish collations, there are letter combinations which sort higher
  than 'Z'.  A test for values > 'WA' was picking up rows where the
  value started with 'Ants Aasma', causing the test to fail.
  Backpatch to 9.2, where the failing test was added.  Per report from
  Svenne Krap and analysis by Jeff Janes

Bruce Momjian pushed:

- Modernize entab source code.  Remove halt.c, improve comments,
  rename manual page file.

Fujii Masao pushed:

- Support TB (terabyte) memory unit in GUC variables.  Patch by Simon
  Riggs, reviewed by Jeff Janes and me.

Tom Lane pushed:

- Add a comment warning against use of pg_usleep() for long sleeps.
  Follow-up to commit 873ab97219caabeb2f7b390268a4fe01e2b7518c, in
  which I noted that WaitLatch was a better solution in the commit log
  message, but neglected to add any documentation in the code.
