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.

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...

    However, my application requires that each collection will also have a
    unique name. Why? So that a human being who wants to modify a collection
    will be able to identify it. It's much harder to know, if you have two
    collections named "Life Science", the the one tagged 24433 is the one
you
    need, and the one tagged 29882 is not

PG_RETURN_BOOL(0) instead of return 0.

from an empty text string.  This makes them consistent with the de facto
behavior of type char's I/O conversion functions, and avoids generating
text values with embedded nulls, which confuse many text operators.

which says that PERFORM will execute any SELECT query and discard the
result.  The former implementation would in fact raise an error if the
result contained more than one row or more than one column.

Also, change plpgsql's error-logging mechanism to emit the additional
messages about error location at NOTICE rather than DEBUG level.  This
allows them to be seen by the client without having to dig into the
postmaster log file (which may be nonexistent or inaccessible by the
client).
