In your original post the error was:

ERROR: prepared statement "S_3" does not
exist

I do not see anything mentioning S_3 in your code sample. Not sure if
that is something the Java tools are supplying or not. Might be
instructive to look at the Postgres server logs when you run the the code.

Have you tried running the code directly against the Postgres server
without going through PgBouncer?
