Yeah.  According to
http://www.postgresql.org/docs/9.4/static/plpgsql-trigger.html#PLPGSQL-EVENT-TRIGGER
only TG_TAG and TG_EVENT are defined inside PL/pgSQL event triggers.

So at present, you can only do very coarse event recording using
PL/pgSQL; if you want to do anything interesting you have to resort
to writing your event trigger in C.  (And I think that even then,
9.4 did not offer very complete facilities for finding out what the
DDL command had done; 9.5 will provide more info.)
