Have you reproduced it on the test machine? A portal is a concept
describing the protocol-level construct to get data from a specific
invocation of a prepared statement. From a quick glance at the code,
what you're seeing here shouldn't happen...
Are you perhaps using the same Connection object from multiple
threads? It is ostensibly supported (
http://jdbc.postgresql.org/documentation/head/thread.html ), but I
wonder if this is what's causing issues. E.g., I haven't worked out
the details, but I think a sequence where two threads send independent
Binds concurrently could cause this.
