From: Phil Thompson <phil@river-bank.demon.co.uk>

Attached is the patch to fix the warning messages from my code.  I also
fixed one which wasn't my code.  Apart from the usual warnings about the
bison/yacc generated code I only have one other warning message.  This
is in gramm.y around line 2234.  I wasn't sure of the fix.

I've also replaced all the calls to free() in gramm.y to calls to
pfree().  Without these I was getting backend crashes with GRANT.  This
might already have been fixed.
