True only to a limited extent. The DBI specifically does *not* take the
'least common denominator' approach which your message implies.

Not true.
DBI drivers are *completely free* to add any features they want
within the extensions mechanisms defined by the DBI. Basically that
simply means that any new methods and any new attributes should begin
with the drivers private prefix ('pg_' for DBD::Pg).
So DBD::Pg can support anything and everything that PostgreSQL offers,
including callbacks.
