No, AFAIK it's just Oracle's syntax.

Can you point to any SQL standard or existing database that uses your
suggestion? Oracle is certainly the de facto standard in this area,
and plpgsql in particular is an unabashed effort to follow their PL/SQL
implementation...
If we decide that we're going to deliberately vary from Oracle's syntax
and semantics, then I have no problem with try/catch as the keywords.
(That's actually my programming heritage as well, I was using exception
handling with those keywords back in the late 70s at HP.)

er ... I'm not clear why type names would have anything to do with
exceptions. What's your vision here exactly?
