I noticed that enums are not available to be queried as binary through
the protocol. Is this a known issue? Too late to fix for 8.3? This
is kind of a pain, because it forces any query that returns an enum to
return the entire result as text. afaik, enums are the only POD type
to behave this way.
postgres=# create type foo as enum('foo');
CREATE TYPE
postgres=# copy (select 'foo'::foo) to '/home/postgres/foo.txt' binary;
ERROR: no binary output function available for type foo
