I failed to reproduce this in 9.3 branch tip. A quick look at the git
history didn't find any obviously-related patches, but certainly there
are enough bugs fixed between 9.3.0 and 9.3.3 that your first move ought
to be to upgrade. If you can still reproduce this with 9.3.3 server
and pg_dump, please submit a *self contained* test case. (The CREATE
TRIGGER statement alone is not that. A SQL script to create a database
that exhibits the problem would do.)
