OK, given that column set for pg_type I guess it really is 7.2 ... you
need to think about an update real soon, because there are a whole lot
of known bugs in the version you are running. At the very least you
should get on to the last release of the 7.2 series, which I think was
7.2.8. But we stopped maintaining 7.2.x at all some years ago. If you
were to move to 8.1 or 8.2 you'd find it a whole lot faster and more
stable.
Anyway, what you seem to have here is a "shell type". It's not doing
anything useful --- you can probably just do a "DROP TYPE trigger".
Or you could just ignore the warning; it's pretty harmless.
