Also, remove the rather useless return value of LockReleaseAll. Change response to detection of corruption in the shared lock tables to PANIC, since that is the only way of cleaning up fully. Originally an idea of Heikki Linnakangas, variously hacked on by Alvaro Herrera and Tom Lane.

communication structure, and make it its own module with its own lock. This should reduce contention at least a little, and it definitely makes the code seem cleaner. Per my recent proposal.

Fix the leak, and add a comment to note that the return value of previous_word must be free'd.

external projects, we should be careful about what parts of the GiST API are considered implementation details, and which are part of the public API. Therefore, I've moved internal-only declarations into gist_private.h -- future backward-incompatible changes to gist.h should be made with care, to avoid needlessly breaking external GiST extensions. Also did some related header cleanup: remove some unnecessary #includes from gist.h, and remove some unused definitions: isAttByVal(), _gistdump(), and GISTNStrategies.

- make sure we always invoke user-supplied GiST methods in a short-lived memory context. This means the backend isn't exposed to any memory leaks that be in those methods (in fact, it is probably a net loss for most GiST methods to bother manually freeing memory now). This also means we can do away with a lot of ugly manual memory management in the GiST code itself. - keep the current page of a GiST index scan pinned, rather than doing a ReadBuffer() for each tuple produced by the scan. Since ReadBuffer() is expensive, this is a perf. win - implement dead tuple killing for GiST indexes (which is easy to do, now that we keep a pin on the current scan page). Now all the builtin indexes implement dead tuple killing. - cleanup a lot of ugly code in GiST

when the blocks list is empty (there can surely be no freelist items if the context contains no memory), and use MemSetAligned not MemSet to clear the headers (we assume alignof(pointer) >= alignof(int32)). Per discussion with Atsushi Ogawa. He proposes some further hacking that I'm not yet sold on, but these two changes are unconditional wins since there is no case in which they make things slower.

When one side of the join has a NULL, we don't want to uselessly try to match it against every remaining tuple of the other side. While at it, rewrite the comparison machinery to avoid multiple evaluations of the left and right input expressions and to use a btree comparator where available, instead of double operator calls. Also revise the state machine to eliminate redundant comparisons and hopefully make it more readable too.
