Allow pg_dumpall to work with previous releases again. Don't pass the -c
option down to pg_dump, where it's useless, and clarify the meaning of -c
in the documentation.
Make sure the pg_dump tar archiver can handle members larger than 2 GB, but
does not create members larger than allowed by the tar format. Also, fix
the generation of the tar header to conform to POSIX.

Remove heap_mark4update from AlterTableCreateToastTable. This has
never been the correct procedure for locking a relation, and the
recently-found ALTER TABLE bug with adding a constraint and a toast
table in the same command shows why it's a bad idea.

Fix some operator-precedence problems. New constructs IS DISTINCT FRM
and IS [NOT] OF were not being parsed consistently with other IS forms.
Also, make the world a little safer for functions named LEFT, RIGHT, etc.
Eliminate the mysterious games that the Cygwin build plays with the linker
flag variables. DLLLIBS is gone, use SHLIB_LINK like everyone else.
Detect cygipc in configure, after the linker flags are set up, otherwise
configure might not work at all.
Make sure everything is covered by make clean.
Fix the build of the new conversion procedure modules.
Add new DLLIMPORT markers where required.
Finally, the compiler complains if we use an explicit
-I/usr/local/include, so don't do that. Curiously, -L/usr/local/lib is
still necessary.

Be careful to include postgres.h *before* any system headers, to ensure
that the right flavors of largefile-related definitions are seen.
Most of these changes are probably unnecessary, but better safe than
sorry.

Guard against send-lots-and-lots-of-data DoS attack from unauthenticated

Avoid multiple scans of utils/mb/conversion_procs/ subdirectories during
'make install'; there are enough of 'em that this slowed down the make
noticeably. Ensure that 'all' is the default make target in all these
directories (defaulting to 'make install' is surprising and dangerous
IMHO). Fix a couple small typos.

EXTRACT(EPOCH FROM timestamp) gave wrong answers in the int64-timestamp

Arrange for the default permissions on a database to allow temp table
creation to world, but disallow temp table creation in template1. Per
latest round of pghackers discussion.
I did not force initdb, but the permissions lockdown on template1 will
not take effect unless you do one (or manually REVOKE TEMP ON DATABASE template1 FROM public).

Work around mktime() brain damage in recent versions of glibc by using
a series of localtime() calls to determine the local timezone offset
when mktime() fails. This eliminates regression failures on RHL 7.3,
and should continue to work until it occurs to the glibc boys to break
localtime() as well. By then I hope we'll have our own timezone code...

Partial solution for 'unexpected EOF' problem with pg_disconnect: it
seems we have a choice between annoying messages and leaking memory
(or dumping core, but that's right out). Patch also fixes several
other problems in pg_disconnect, such as being willing to close a
channel that isn't a PG channel.

pg_on_connection_loss command for libpgtcl. Patch from
Gerhard Hintermayer, revised and documented by Tom Lane.
This patch also fixes a 'must fix' bug: libpgtcl's LISTEN/NOTIFY
support was broken by the recent changes to the PGnotify structure.
Guess that change wasn't quite so safe as we thought.
