Is there any table in postgres ,for eg pg_constraints, where in i can get the references for all the fields of a particular table in the data base?
Consider this..
I have
item master -- Item_code, Item Name
supplier master -- supplier_code, supplier_name
supplier_item_catalogue -- supplier_code references supplier master, item_code references item master
Now , if i select table supplier_item_catalogue for any reason from pg_tables, i should know that related tables item_master and supplier_master are also to be selected.
How can i do this using php /postgres?

There's some help in techdocs.postgresql.org, in the mini-HOWTO I wrote on
Hacking the Referential Integrity Tables. This should point you in the
right direction.
