pghackers. This fixes the problem recently reported by Markus KrÌutner (hash bucket split corrupts the state of scans being done concurrently), and I believe it also fixes all the known problems with deadlocks in hash index operations. Hash indexes are still not really ready for prime time (since they aren't WAL-logged), but this is a step forward.

killed items; just skip to the next item immediately. Only check for key equality when we reach a non-killed item or the end of the index page. This saves key comparisons when there are lots of killed items, as for example in a heavily-updated table that's not been vacuumed lately. Seems to be a win for pgbench anyway.

config file if it exists. This was already discussed as being a good idea, and now seems the cleanest way to deal with initdb-time failures on machines with small SHMMAX. (The submitted patches instead modified initdb.sh to pass the correct sizing parameters, but that would still leave standalone backends prone to failure later. An admin who needs to use a standalone backend has enough trouble already, he shouldn't have to manually configure its shmem settings...)

layout; therefore, this change forces REINDEX of hash indexes (though not a full initdb). Widen hashm_ntuples to double so that hash space management doesn't get confused by more than 4G entries; enlarge the allowed number of free-space-bitmap pages; replace the useless bshift field with a useful bmshift field; eliminate 4 bytes of wasted space in the per-page special area.

scheme. A pleasant side effect is that it is *much* faster when deleting a large fraction of the indexed tuples, because of elimination of redundant hash_step activity induced by hash_adjscans. Various other continuing code cleanup.

yet). Fix a couple of bugs that would only appear if multiple bitmap pages are used, including a buffer reference leak and incorrect computation of bit indexes. Get rid of 'overflow address' concept, which accomplished nothing except obfuscating the code and creating a risk of failure due to limited range of offset field. Rename some misleadingly-named fields and routines, and improve documentation.
