For individual tables, client interfaces usually have a way to show the table definition. In psql, for example, you can use "\d tablename". If you want to see all foreign key constraints for all tables then you could query the pg_constraint system catalog. http://www.postgresql.org/docs/8.0/static/catalog-pg-constraint.html You can get an idea of what query to issue by viewing the hidden commands that psql executes (run "psql -E" or execute "\set ECHO_HIDDEN" and then execute "\d tablename"). Here's an example: SELECT conrelid::regclass, conname, pg_get_constraintdef(oid) FROM pg_constraint WHERE contype = 'f'; -- Michael Fuhr http://www.fuhr.org/~mfuhr/ ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
