this someday, but right now it seems that posix_fadvise is immature to the point of being broken on many platforms ... and we don't have any benchmark evidence proving it's worth spending time on.

per-tuple space overhead for sorts in memory. I chose to replace the previous patch that tried to write out the bare minimum amount of data when sorting on disk; instead, just dump the MinimalTuples as-is. This wastes 3 to 10 bytes per tuple depending on architecture and null-bitmap length, but the simplification in the writetup/readtup routines seems worth it.

analyzing, so that future analyze threshold calculations don't get confused. Also, make sure we correctly track the decrease of live tuples cause by deletes. Per report from Dylan Hansen, patches by Tom Lane and me.

tuples with less header overhead than a regular HeapTuple, per my recent proposal. Teach TupleTableSlot code how to deal with these. As proof of concept, change tuplestore.c to store MinimalTuples instead of HeapTuples. Future patches will expand the concept to other places where it is useful.

will be expanded to a list of their member fields, rather than creating a nested rowtype field as formerly. (The old behavior is still available by omitting '.*'.) This syntax is not allowed by the SQL spec AFAICS, so changing its behavior doesn't violate the spec. The new behavior is substantially more useful since it allows, for example, triggers to check for data changes with 'if row(new.*) is distinct from row(old.*)'. Per my recent proposal.

palloc() will normally round allocation requests up to the next power of 2, so make dynahash choose allocation sizes that are as close to a power of 2 as possible. Back-patch to 8.1 --- the problem exists further back, but a much larger patch would be needed and it doesn't seem worth taking any risks.

opposed to what other versions apparently do, so it's not safe to print an error message. Besides, getopt_long itself already did, so it's redundant anyway.

After updating to the latest cvs, and also building most of the addons (like PLs), the following patch is neededf for win32 + Visual C++. * Switch to use the new win32 semaphore code * Rename win32_open to pgwin32_open. win32_open collides with symbols defined in Perl. MingW didn't detect ig, MSVC did. And it's a bit too generic a name to export globally, imho... * Python defines some partially broken #pragmas in the headers when doing a debug build. Workaround.
