Two functions? An operator only has one underlying function.
(Aggregates have as many as three though.)

The default contents of pg_description come from the DESCR() macros in
include/catalog/*.h. It looks like only pg_proc and pg_type have any
useful info in them in the current state of the source. I'm guessing
that psql's \do actually looks for a description attached to the
underlying function, rather than one attached to the operator.
