vacuum/analyze timestamp columns at the end, rather than at a random
spot in the middle as in the original patch.  This was deemed more usable
as well as less likely to break existing application code.  initdb forced
accordingly.  In passing, remove former kluge for initializing
pg_stat_file()'s pg_proc entry --- bootstrap mode was fixed recently
so that this can be done without any hacks, but I overlooked this usage.

commutator operators, and mark hash-opclass members as oprcanhash.
This is a pretty ugly, brute-force solution, but it seems that getting
rid of all these redundant-looking operators would require some tweaks
in the core operator-resolution code to behave nicely, and I'm not
willing to risk that just before RC1.

This patch, against xfunc.sgml, adds a new subsection 33.9.12, Shared
Memory and LWLocks in C-Language Functions, describing how shared memory
and lwlocks may be requested by C add-in functions.

AbortTransaction, which would lead to recursion and eventual PANIC exit
as illustrated in recent report from Jeff Davis.  First, in xact.c create
a special dedicated memory context for AbortTransaction to run in.  This
solves the problem as long as AbortTransaction doesn't need more than 32K
(or whatever other size we create the context with).  But in corner cases
it might.  Second, in trigger.c arrange to keep pending after-trigger event
records in separate contexts that can be freed near the beginning of
AbortTransaction, rather than having them persist until CleanupTransaction
as before.  Third, in portalmem.c arrange to free executor state data
earlier as well.  These two changes should result in backing off the
out-of-memory condition before AbortTransaction needs any significant
amount of memory, at least in typical cases such as memory overrun due
to too many trigger events or too big an executor hash table.  And all
the same for subtransaction abort too, of course.

some of the Windows-only makefiles; the correct place to assert these
things is pg_config.h.win32.  Per bug #2677.

zic's Europe/London, rather than Europe/Dublin as before.  This seems
a less surprising choice, particularly with respect to dates before
1948.  Original suggestion was to translate to straight GMT, but this
seems wrong given that these zones *are* DST-aware.  Per offlist
discussion with Magnus.

problem of memory leakage in plpgsql exception handling, but it should
get rid of the lion's share of leakage.

because on that platform strftime produces localized zone names in varying
encodings.  Even though it's only in a comment, this can cause encoding
errors when reloading the dump script.  Per suggestion from Andreas
Seltenreich.  Also, suppress %Z on Windows in the %s escape of
log_line_prefix ... not sure why this one is different from the other two,
but it shouldn't be.

python 2.5.  This involves fixing several violations of the published

Windows), arrange for each postmaster child process to be its own process
group leader, and deliver signals SIGINT, SIGTERM, SIGQUIT to the whole
process group not only the direct child process.  This provides saner behavior
for archive and recovery scripts; in particular, it's possible to shut down a
warm-standby recovery server using "pg_ctl stop -m immediate", since delivery
of SIGQUIT to the startup subprocess will result in killing the waiting
recovery_command.  Also, this makes Query Cancel and statement_timeout apply
to scripts being run from backends via system().  (There is no support in the
core backend for that, but it's widely done using untrusted PLs.)  Per gripe
from Stephen Harris and subsequent discussion.
