The failure to COMMIT is a programmer error - ROLLBACK's much safer.  At  least that's what we decided in the AOLserver community, and that's 
what the drivers for Oracle and PG (the two I maintain) implement.

The connection pooling mechanism needs to track the transaction state 
and only ROLLBACK a handle that's not in autocommit state or in the 
midst of a BEGIN/END transaction (again, Oracle vs. PG)..
