Not using any standard JDBC method. However, you could do what psql does,
and that is connect to the template1 database (which always exists), and
then issue a query on the system tables.

Yes. Once you have a Connection, get a DatabaseMetaData object (using
getMetaData() ), and use the getTables() method.
