That's not really true. You can't really add abs(x) or hash(x) right now because the current code only supports this syntax: \set varname operand1 [ operator operand2 ] There's no way to add support for a unary operator with that syntax. -- 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
