We have successfully upgraded Hibernate, but we no longer able to ingest any data into our PostgreSQL 9.1.4 database. It is as if, from the hibernate perspective the database is in read-only mode. Data can be successfully ingested via psql into the target tables with no issues. We would like to rule out Hibernate configuration as the culprit.

Here is our hibernate.properties file.

Question: Are there parameters that are missing that now need to be included?
Question: Are any of these parameters we have set, now obsolete?

Thanks
