This is not possible. Connection is obtained to the database, not to the
server. Transactions are database-bound, not server-bound.

Catalogs are not supported by Firebird (see DatabaseMetaData results).

Please describe your requirement in details. Why do you need to switch the
database in the same connection? Why wouldn't be enough to use another
connection?
