in plpgsql: they fail for datatypes that have old-style I/O functions
due to caching FmgrInfo structs with wrong fn_mcxt lifetime.

Although the plpython fix seems straightforward, I can't check it here
since I don't have Python installed --- would someone check it?

right, but it failed to get the padding case right.

This was obscured by subsequent application of bpchar() in all but one
regression test case, and that one didn't fail in an obvious way ---
trailing blanks are hard to see.  Add another test case to make it
more obvious if it breaks again.

calls.  This has never actually cached anything, because postgres.c does
each fastpath call as a separate transaction command, and so fastpath.c
would always decide that its cache was outdated.  If it had worked, it
would now be failing for calls of oldstyle functions due to dangling
pointers in the FmgrInfo struct.  Rip it out for simplicity and bug-
proofing.

report on old-style functions invoked by RI triggers.  We had a number of
other places that were being sloppy about which memory context FmgrInfo
subsidiary data will be allocated in.  Turns out none of them actually
cause a problem in 7.1, but this is for arcane reasons such as the fact
that old-style triggers aren't supported anyway.  To avoid getting burnt
later, I've restructured the trigger support so that we don't keep trigger
FmgrInfo structs in relcache memory.  Some other related cleanups too:
it's not really necessary to call fmgr_info at all while setting up
the index support info in relcache entries, because those ScanKeyEntry
structs are never used to invoke the functions.  This should speed up
relcache initialization a tiny bit.

because cached fmgr info contained reference to a shorter-lived data
structure.  Also guard against possibility that fmgr_info could fail,

basically want your guys feedback.  I have sprinkled some of my q's thru
the text delimited with the @@ symbol.  It seems to work perfectly.

[ Removed @@ comments because patch was reviewed. ]

At the moment it does CHECK constraints only, with inheritance.  However,
due to the problem mentioned before with the mismatching between inherited
constraints it may be wise to disable the inheritance feature for a while.
it is written in an extensible fashion to support future dropping of other
types of constraint, and is well documented.

Please send me your comments, check my use of locking, updating of
indices, use of ERROR and NOTICE, etc. and I will rework the patch based
on feedback until everyone
is happy with it...
