Also applied patch from Lars Stenberg to make callable statements use the form select * from func() when running against a 7.3 server instead of select func() to allow for set returning functions to be called.

rid of the assumption that sizeof(Oid)==sizeof(int). This is one small step towards someday supporting 8-byte OIDs. For the moment, it doesn't do much except get rid of a lot of unsightly casts.

locParam lists can be converted to bitmapsets to speed updating. Also, replace 'locParam' with 'allParam', which contains all the paramIDs relevant to the node (i.e., the union of extParam and locParam); this saves a step during SetChangedParamList() without costing anything elsewhere.

Instead of Lists of integers, we now store variable-length bitmap sets. This should be faster as well as less error-prone.

Instead of grovelling through pg_class to find them, make use of the handy dandy dependency mechanism: just delete everything that depends on our temp schema. Unlike the pg_class scan, the dependency mechanism is smart enough to delete things in an order that doesn't fall foul of any dependency restrictions. Fixes problem reported by David Heggie: a temp table with a serial column may cause a backend FATAL exit at shutdown time, if it chances to try to delete the temp sequence first.

expression accepted by the regex operators, per discussion yesterday. Along the way, reduce deadlock_timeout from PGC_POSTMASTER to PGC_SIGHUP category. It is probably best to insist that all backends share the same setting, but that doesn't mean it has to be frozen at startup.

nodes where it's not really necessary. In many cases where the scan node is not the topmost plan node (eg, joins, aggregation), it's possible to just return the table tuple directly instead of generating an intermediate projection tuple. In preliminary testing, this reduced the CPU time needed for 'SELECT COUNT(*) FROM foo' by about 10%.
