Using the unknown oid seems like it'd introduce more problems:
overloading, and the possibility you actually pass your array as some
other type unexpectedly.

I am wondering if the right way to find the array OID is to prepend "_"
and search on pg_type.typname, or to look for pg_type.typinput = (oid of
array_in) and pg_type.typelem = (oid of underlying type). Is there a
'standard' way of finding an array type OID?
