Re: [JDBC] postgresql-jdbc driver not respecting prepareThreshold=0

I am running an application in wildfly 9.0.2 using postgres 9.2.19 databases accessed through pgBouncer 1.7.2 in transaction pooling mode. With recent versions of postgresql-jdbc, the application is failing with prepared statement does not exist errors.

The database connections have preparedThreshold set to 0 as documented in the pgBouncer FAQ (https://pgbouncer.github.io/faq.html#how-to-use-prepared-statements-with-transaction-pooling).

This works with postgresql-jdbc versions 9.4-1205 and 9.4.1208. It does not work in any version since 1208.

I would like to keep packages up-to-date, so any help is much appreciated. Packages are centos 6, pgdg 9.2, and wildfly .tar.gz.

Stack traces and configuration follow below.

Thanks,

Malcolm Studd



The stack trace from 9.4.1212. The reported error is the same in 1211, and I think 1210.
