If you had checked the archives you could have established that this
has not been done yet: it is possible to return record sets to java
code, but not via a CallableStatement.

I have written a patch that allows PostgreSQL to do that.

I'll send it to you if you want.

Stored procedures, stored functions... all the same. The generic term
for imperative code executed within the database server is "stored
proc". PostgreSQL's implementation of stored procs can return only one
value.
