PostgreSQL has many built in types and only the basic ones are directly supported here. All forms of integer database types are returned as integer values. All forms of float and real types are returned as float values. Boolean is returned as "t" or "f". All other types, including arrays are returned as strings formatted in the same default PostgreSQL manner that you would see in the psql program. Database NULL values are returned as NULL.
FALSE is returned if row exceeds the number of rows in the set, or on any other error.
