It turns out that Python 2.2 is the oldest version that PL/Python compiles
with, apparently related to the introduction of iterators.  Might as well
document this.

Per Andreas Wenk, Andres Freund and Rob Wultsh.  Thanks, Robert Haas, for the
patch.

The code in the new block was not reindented; it will be fixed by pgindent
eventually.

Backpatch to 8.4.X.

seconds, per gripe from Richard Neill.  Also, add a cross-reference to
the to_timestamp function.

There are probably still some adjustments to be made in the details
of the output, but this gets the basic structure in place.

Re-add documentation for --no-readline option of psql, mistakenly removed a decade ago. Backpatch to release 7.4.

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.

Per comment from Simon.

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.

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.

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.

appears to explain the recent reports of "PANIC: cannot make new WAL entries
during recovery".

Noticed by Itagaki Takahiro.

Main problem found by Muhammad Aqeel, some cosmetic additions by me.

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.

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.

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.

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.

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.

Adds the ability to retrieve async notifications using dblink,
via the addition of the function dblink_get_notify(). Original patch

review and adjustments by Joe Conway.

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.

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.

source files that need it.

run when built with --with-openssl).

Add bytea.h inclusions as needed.  Some of the contrib regression tests
need to be de-hexified, too.  Per buildfarm.
