Not a real flag, but only by having a look at the string when, e.g.
querying.

select mon$attachment_name From mon$attachments

or via a context variable.

select rdb$get_context('SYSTEM', 'DB_NAME') from rdb$database


But, AFAIK, later dismisses the full path information only, if
DatabaseAccess in firebird.conf is set to None:

DatabaseAccess = None

but then, you only allow alias connections anyway. ;-)
