I tried postgres-jdbc driver and use PrepareStatement. Backend could
receive `bind` and `execute` message, but the portal name is still empty.
How can I specify the portal name?

This seems like a question better posed to the JDBC list as opposed to
-hackers. The protocol can technically (from the description of
parse+bind) handle what you describe but whether this specific client
provides access to the capability is outside the scope of this list. I
will say that there doesn't seem to be a way in pure SQL to use a prepared
statement and have it create a named portal (PREPARE not allowing DECLARE
to be the underlying statement).

You may wish to describe what you are trying to do at a higher level. If
it is something like the above you might find a solution to your
unspecified problem by using cursors within a pl/pgsql function.
