happened to be right up against the end of memory, per report from
Matt Magoffin. While at it, avoid useless multiple copying of string
by not depending on xmlStrncatNew.
Allow tag and entity names that follow XML rules. Provide for hexadecimal
as well as decimal numeric entities. Adjust code names to coincide with
new descriptions.
GetMemoryChunkSpace, not just the palloc request size. This brings the
allocatedMemory counter close enough to reality (as measured by
MemoryContextStats printouts) that I think we can get rid of the arbitrary
factor-of-2 adjustment that was put into the code initially. Given the
sensitivity of GIN build to work memory size, not using as much of work
memory as we're allowed to seems a pretty bad idea.
Else, in a 64-bit machine with maintenance_work_mem set to above 4Gb,
the counter overflows and we never recognize having reached the
maintenance_work_mem limit. I believe this explains out-of-memory
failure recently reported by Sean Davis.
This is a bug, so backpatch to 8.2.
it failed for splits of non-leaf pages because in such pages the first
data key on a page is suppressed, and so we can't just copy the first
key from the right page to reconstitute the left page's high key.

checkpoint. This guards against an unlikely data-loss scenario in which
we re-use the relfilenode, then crash, then replay the deletion and
recreation of the file. Even then we'd be OK if all insertions into the
new relation had been WAL-logged ... but that's not guaranteed given all
the no-WAL-logging optimizations that have recently been added.

of this seems a bit marginal, if it's useful enough to be shown in the manual
then we probably ought to support doing it without double evaluation of the
ts_rank function. Per my proposal earlier today.
gives the old behavior; selecting false allows the dictionary to be used
as a filter ahead of other dictionaries, because it will pass on rather
than accept words that aren't in its stopword list.

itself as libuuid, not libossp-uuid which was the only case expected by
our build support. Install a configure test to determine which name
to use (and to check that the library is present at all).
even in code paths where we don't pay any subsequent attention to the typmod
value. This seems needed in view of the fact that 8.3's generalized typmod
support will accept a lot of bogus syntax, such as "timestamp(foo)" or
"record(int, 42)" --- if we allow such things to pass without comment,
users will get confused. Per a recent example from Greg Stark.
To implement this in a way that's not very vulnerable to future
bugs-of-omission, refactor the API of parse_type.c's TypeName lookup routines
so that typmod validation is folded into the base lookup operation. Callers
can still choose not to receive the encoded typmod, but we'll check the
decoration anyway if it's present.
uninitialized value, and avoid invoking the function nine separate
times in the pg_xmlIsNameChar macro. Should resolve buildfarm failures.
Per report from Ben Leslie.
