[HACKERS] querying system catalogs to extract foreign keys

[jiby george]

I wanted to extract foriegn keys from the postgresql database related
to each of the tables.. I tried to use the getImportedKeys and
getExportedKeys of java.sql.DatabaseMetadata... But it didnt give any
expected results... So can anyone tell me how to query the system
catalogs to extract this info??
Thanx
Jiby
