Avoid testing tuple visibility without buffer lock in RI_FKey_check().

2016-10-23T19:01:24+00:00

Despite the argumentation I wrote in commit 7a2fe85b0, it's unsafe to do
this, because in corner cases it's possible for HeapTupleSatisfiesSelf
to try to set hint bits on the target tuple; and at least since 8.2 we
have required the buffer content lock to be held while setting hint bits.

The added regression test exercises one such corner case.  Unpatched, it
causes an assertion failure in assert-enabled builds, or otherwise would
cause a hint bit change in a buffer we don't hold lock on, which given
the right race condition could result in checksum failures or other data
consistency problems.  The odds of a problem in the field are probably
pretty small, but nonetheless back-patch to all supported branches.

Report: <19391.1477244876@sss.pgh.pa.us>

Improve documentation about use of Linux huge pages.

2016-10-22T18:04:51+00:00

Show how to get the system's huge page size, rather than misleadingly
referring to PAGE_SIZE (which is usually understood to be the regular
page size).  Show how to confirm whether huge pages have been allocated.
Minor wordsmithing.  Back-patch to 9.4 where this section appeared.

Doc: wording tweak for PERL, PYTHON, TCLSH configuration variables.

2016-10-21T15:01:49+00:00

Replace "Full path to ..." with "Full path name of ...".  At least one
user has misinterpreted the existing wording as meaning "Directory
containing ...".

Fix EXPLAIN so that it doesn't emit invalid XML in corner cases.

2016-10-20T21:18:05+00:00

With track_io_timing = on, EXPLAIN (ANALYZE, BUFFERS) will emit fields
named like "I/O Read Time".  The slash makes that invalid as an XML
element name, so that adding FORMAT XML would produce invalid XML.

We already have code in there to translate spaces to dashes, so let's
generalize that to convert anything that isn't a valid XML name character,
viz letters, digits, hyphens, underscores, and periods.  We could just
reject slashes, which would run a bit faster.  But the fact that this went
unnoticed for so long doesn't give me a warm feeling that we'd notice the
next creative violation, so let's make it a permanent fix.

Reported by Markus Winand, though this isn't his initial patch proposal.

Back-patch to 9.2 where track_io_timing was added.  The problem is only
latent in 9.1, so I don't feel a need to fix it there.

Discussion:

Sync our copy of the timezone library with IANA release tzcode2016h.

2016-10-20T19:40:22+00:00

This absorbs a fix for a symlink-manipulation bug in zic that was
introduced in 2016g.  It probably isn't interesting for our use-case,
but I'm not quite sure, so let's update while we're at it.

Update time zone data files to tzdata release 2016h.

2016-10-20T19:20:26+00:00

(Didn't I just do this?  Oh well.)

DST law changes in Palestine.  Historical corrections for Turkey.
Switch to numeric abbreviations for Asia/Colombo.

Another portability fix for tzcode2016g update.

2016-10-20T03:32:58+00:00

clang points out that SIZE_MAX wouldn't fit into an int, which means
this comparison is pretty useless.  Per report from Thomas Munro.
