You could query the system catalogs or the Information Schema (the latter available in 7.4 and later). Another way would be to query the tables themselves and use the functions described under "Retrieving Query Result Information" in the libpq documentation. http://www.postgresql.org/docs/8.0/interactive/catalogs.html http://www.postgresql.org/docs/8.0/interactive/information-schema.html http://www.postgresql.org/docs/8.0/interactive/libpq-exec.html#LIBPQ-EXEC-SELECT-INFO -- Michael Fuhr http://www.fuhr.org/~mfuhr/ ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
