+<h2>Applied Patches</h2>
+<p>
+Tatsuo Ishii committed:
+</p>
+
+<p>
+- Multi-threaded version of pgbench contributed by ITAGAKI Takahiro,
+ reviewed by Greg Smith and Josh Williams.
+</p>
+
+<p>
+Tom Lane committed:
+</p>
+
+<p>
+- Portability and documentation fixes for threaded pgbench patch.
+</p>
+
+<p>
+- Cause pg_proc.probin to be declared as text, not bytea. Everything
+ was already treating it as text anyway, to the point that I couldn't
+ find anything to change except the datatype markings in catalog/*.h.
+ The only effect that the bytea declaration had was to cause
+ byteaout() to be invoked when pg_dump (or another client program)
+ inspected the column value. Since pg_dump wasn't expecting that,
+ but just treating what it got as text, the net result is that dump
+ and reload would mangle any backslashes or non-ASCII characters in
+ the filename string for a C-language function. That is a very
+ long-standing bug, but given the lack of field complaints it doesn't
+ seem worth trying to find a back-patchable fix. We'll just make
+ this change to fix it going forward. This change will also
+ forestall problems after the planned change to let bytea emit hex
+ output instead of escaped characters.
+</p>
+
+<p>
+- Support hex-string input and output for type BYTEA. Both hex format
+ and the traditional "escape" format are automatically handled on
+ input. The output format is selected by the new GUC variable
+ bytea_output. As committed, bytea_output defaults to HEX, which is
+ an *incompatible change*. We will keep it this way for awhile for
+ testing purposes, but should consider whether to switch to the more
+ backwards-compatible default of ESCAPE before 8.5 is released.
+ Peter Eisentraut
+</p>
+
+<p>
+- In pgsql/src/interfaces/libpq/fe-exec.c, teach PQescapeByteaConn()
+ to use hex format when the target connection is to a server >= 8.5.
+ Per my proposal in discussion of hex-format patch.
+</p>
+
+<p>
+- Ooops, missed that a couple of contrib modules have calls to
+ byteacmp. Add bytea.h inclusions as needed. Some of the contrib
+ regression tests need to be de-hexified, too. Per buildfarm.
+</p>
+
+<p>
+- In pgsql/src/bin/pg_dump/pg_dump.c, suppress pointer-signedness
+ warning.
+</p>
+
+<p>
+- Fix some more regression tests (missed these because they're only
+ run when built with --with-openssl).
+</p>
+
+<p>
+- Fix an ecpg test, too. Are we there yet?
+</p>
+
+<p>
+- Fix pg_dump to do the right thing when escaping the contents of
+ large objects. The previous implementation got it right in most
+ cases but failed in one: if you pg_dump into an archive with
+ standard_conforming_strings enabled, then pg_restore to a script
+ file (not directly to a database), the script will set
+ standard_conforming_strings = on but then emit large object data as
+ nonstandardly-escaped strings. At the moment the code is made to
+ emit hex-format bytea strings when dumping to a script file. We
+ might want to change to old-style escaping for backwards
+ compatibility, but that would be slower and bulkier. If we do, it's
+ just a matter of reimplementing appendByteaLiteral(). This has been
+ broken for a long time, but given the lack of field complaints I'm
+ not going to worry about back-patching.
+</p>
+
+<p>
+- Add matchorig, matchsynonyms, and keepsynonyms options to
+ contrib/dict_xsyn. Sergey Karpov.
+</p>
+
+<p>
+- Improve plpgsql's ability to cope with rowtypes containing dropped
+ columns, by supporting conversions in places that used to demand
+ exact rowtype match. Since this issue is certain to come up
+ elsewhere (in fact, already has, in ExecEvalConvertRowtype), factor
+ out the support code into new core functions for tuple conversion.
+ I chose to put these in a new source file since heaptuple.c is
+ already overly long. Heavily revised version of a patch by Pavel
+ Stehule.
+</p>
+
+<p>
+- Fix some omissions in the dependency-object-class support for
+ SQL/MED objects. Main problem found by Muhammad Aqeel, some
+ cosmetic additions by me.
+</p>
+
+<p>
+- Remove long-since-unused file commands/version.h. Noticed by
+ Itagaki Takahiro.
+</p>
+
+<p>
+- In pgsql/src/backend/access/transam/xlog.c, rm_cleanup functions
+ need to be allowed to write WAL entries. This oversight appears to
+ explain the recent reports of "PANIC: cannot make new WAL entries
+ during recovery".
+</p>
+
+<p>
+- In pgsql/src/bin/psql/copy.c, try to defend against the possibility
+ that libpq is still in COPY_IN state when we reach the post-COPY
+ "pump it dry" error recovery code that was added 2006-11-24. Per a
+ report from Neil Best, there is at least one code path in which this
+ occurs, leading to an infinite loop in code that's supposed to be
+ making it more robust not less so. A reasonable response seems to
+ be to call PQputCopyEnd() again, so let's try that. Back-patch to
+ all versions that contain the cleanup loop.
+</p>
+
+<p>
+- Modify parallel pg_restore to track pending and ready items by means
+ of two new lists, rather than repeatedly rescanning the main TOC
+ list. This avoids a potential O(N^2) slowdown, although you'd need
+ a *lot* of tables to make that really significant; and it might
+ simplify future improvements in the scheduling algorithm by making
+ the set of ready items more easily inspectable. The original
+ thought that it would in itself result in a more efficient job
+ dispatch order doesn't seem to have been borne out in testing, but
+ it seems worth doing anyway.
+</p>
+
+<p>
+- In pgsql/src/backend/access/transam/xlog.c, document that
+ LocalSetXLogInsertAllowed can be re-executed. Per comment from
+ Simon Riggs.
+</p>
+
+<p>
+Joe Conway committed:
+</p>
+
+<p>
+- Implement has_sequence_privilege() Add family of functions that did
+ not exist earlier, mainly due to historical omission. Original
+ patch by Abhijit Menon-Sen, with review and modifications by Joe
+ Conway. catversion.h bumped.
+</p>
+
+<p>
+- Implement dblink_get_notify(). Adds the ability to retrieve async
+ notifications using dblink, via the addition of the function
+ dblink_get_notify(). Original patch by Marcus Kempe, suggestions by
+ Tom Lane and Alvaro Herrera, patch review and adjustments by Joe
+ Conway.
+</p>
+
+<p>
+Alvaro Herrera committed:
+</p>
+
+<p>
+- Avoid including miscadmin.h into plpgsql.h; instead include it into
+ the two source files that need it.
+</p>
+
+<p>
+- Fix manpages related to SPI functions. This patch adds declaration
+ so that they end up in section 3, and adds them to the Makefiles to
+ install them. Also, some synopses needed reflowing so that they
+ look nice in 80-column terminals.
+</p>
+
+<p>
+- Document that autovacuum may run ANALYZE.
+</p>
+
+<p>
+Peter Eisentraut committed:
+</p>
+
+<p>
+- Use DocBook XSL stylesheets for man page building This switches the
+ man page building process to use the DocBook XSL stylesheet
+ toolchain. The previous targets for Docbook2X are removed.
+ configure has been updated to look for the new tools. The
+ Documentation appendix contains the new build instructions. There
+ are also a few isolated tweaks in the documentation to improve
+ places that came out strangely in the man pages.
+</p>
+
+<p>
+- Expand test coverage support to entire tree. Test coverage support
+ now covers the entire source tree, including contrib, instead of
+ just src/backend. In a related but independent development, the
+ commands make coverage and make coverage-html can be run in any
+ directory. This turned out to be much easier than feared. Besides
+ a few ad hoc fixes to pass the make target down the tree, change all
+ affected makefiles to list their directories in the SUBDIRS
+ variable, changed from variants like DIRS and WANTED_DIRS. MSVC
+ build fix was attempted as well.
+</p>
+
+<p>
+- Ship documentation without intermediate tarballs. Documentation
+ files in HTML and man formats are now prepared for distribution
+ using the distprep make target, like everything else. They are
+ placed in doc/src/sgml/html and manX and installed from there by
+ make install, if present. The business with the tarballs in the
+ tarball is gone.
+</p>
+
+<p>
+Michael Meskes committed:
+</p>
+
+<p>
+- In pgsql/src/interfaces/ecpg/preproc/ecpg.c, fixed copyright notice.
+</p>
+
+<p>
+- Added STRING datatype for Informix compatibility mode. This work is
+ based on a patch send in by Zoltan Boszormenyi.
+</p>
+
+<p>
+Heikki Linnakangas committed:
+</p>
+
+<p>
+- Improve error messages in md.c. When a filesystem operation like
+ open() or fsync() fails, say "file" rather than "relation" when
+ printing the filename. This makes messages that display block
+ numbers a bit confusing. For example, in message 'could not read
+ block 150000 of file "base/1234/5678.1"', 150000 is the block number
+ from the beginning of the relation, ie. segment 0, not 150000th
+ block within that segment. Per discussion, users aren't usually
+ interested in the exact location within the file, so we can live
+ with that. To ease constructing error messages, add
+ FilePathName(File) function to return the pathname of a virtual fd.
+</p>
+
+<p>
+- In pgsql/src/backend/postmaster/postmaster.c, fast shutdown stop
+ should forcibly disconnect any active backends, even if a smart
+ shutdown is already in progress. Backpatch to 8.3, this was broken
+ in the patch that introduced "dead-end backends". Per report by
+ Itagaki Takahiro, patch by Fujii Masao.
+</p>
+
+<p>
+Magnus Hagander committed:
+</p>
+
+<p>
+- In pgsql/src/backend/postmaster/postmaster.c, avoid terminating the
+ postmaster on a number of "can't happen" cases during backend
+ startup on Win32. Instead, log the error and just forget about the
+ potentially dangling process, since we can't do anything about it
+ anyway.
+</p>
+
+<p>
+Bruce Momjian committed:
+</p>
+
+<p>
+- In pgsql/src/interfaces/ecpg/ecpglib/data.c, remove unused ecpg
+ variable.
+</p>
