You sure it's not something newer? There wasn't any built-in type named
"trigger" in 7.2 --- there is in 7.3 and up.
Assuming it is 7.3, dropping the type would be a really bad idea. Could
we see the results of "select * from pg_type where typname = 'trigger'"?
I'm guessing that either that row is corrupt, or you dropped the
original superuser account (in which case the gripe about type trigger
is just the tip of the iceberg).
