Rule flag in gram.y - Mailing list pgsql-hackers

There is some code in gram.y that detects whether you are in a RULE so
NEW/OLD can be detected.  Seems the value is reset on parser start and
set on RULE start, but not reset on rule and.  A multi-query string
could use NEW/OLD in the queries after the RULE even though they are
invalid.  The following patch fixes this by resetting the flag when the
rule action happens.
