I think it's right the way it is. The parser constructs a VacuumStmt for either a VACUUM or an ANALYZE command. That statement is checking that if you are doing an ANALYZE, you can't specify FULL or FREEZE. That makes sense, because there is no ANALYZE FULL or ANALYZE FREEZE command. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
