pgsql: Add a new DestReceiver for printing tuples without catalog acces

Add a new DestReceiver for printing tuples without catalog access.

If you create a DestReciver of type DestRemote and try to use it from
a replication connection that is not bound to a specific daabase, or
any other hypothetical type of backend that is not bound to a specific
database, it will fail because it doesn't have a pg_proc catalog to
look up properties of the types being printed. In general, that's
an unavoidable problem, but we can hardwire the properties of a few
builtin types in order to support utility commands. This new
DestReceiver of type DestRemoteSimple does just that.

Patch by me, reviewed by Michael Paquier.
