pgsql: Fix thinko in tok_is_keyword(): it was looking at the wrong union - Mailing list pgsql-committers

Log Message:
-----------
Fix thinko in tok_is_keyword(): it was looking at the wrong union variant
of YYSTYPE, and hence returning the wrong answer for cases where a plpgsql
"unreserved keyword" really does conflict with a variable name.  Obviously
I didn't test this enough :-(.  Per bug #5524 from Peter Gagarinov.
