Anybody have an Oracle PL/SQL reference at hand?

Can anyone check how well the syntax of plpgsql EXCEPTION, as described
at
http://developer.postgresql.org/docs/postgres/plpgsql-control-structures.html#PLPGSQL-ERROR-TRAPPING
agrees with what Oracle does?  I did some googling but couldn't find
anything that seemed authoritative.  I'm wondering in particular if
Oracle allows multiple condition names per WHEN, along the lines ofWHEN condition [ , condition ... ] THEN
handler_statements

Also it would be nice to see a complete list of the "condition" names
that they accept.  I whipped up a quick table based on our ERRCODE
macro names, see
http://developer.postgresql.org/cvsweb.cgi/pgsql-server/src/pl/plpgsql/src/plerrcodes.h
but I'm certain that's not what we really want to expose to users
in the long run.
