ISSUE: The PDO Firebird driver does not support catching Firebird Events.
REQUEST: Add Event callback registration to the Firebird PDO driver

BACKGROUND:
The standard PHP vendor specific driver for Firebird supports the Firebird Database Event feature:

POST_EVENT '<event_name>';

with the following function to catch events:
resource ibase_set_event_handler (..);

Events are a very powerful feature of Firebird.

Migrating to PDO from the standard firebird extension is impossible if Events are used in the PHP code.
