PostgreSQL JDBC Driver 9.3 is a major release of the PostgreSQL JDBC Driver. This release has introduced new functionality and significant changes to the existing PostgreSQL JDBC Driver application. If you are upgrading from any prior version of the PostgreSQL JDBC Driver to PostgreSQL JDBC Driver 9.3, there is a HIGH RISK of data loss and downtime if you do not carefully test your existing database and application with this new version. |
eApps recommends, as a best practice, to maintain a staging server where you can test software upgrades before moving them into production. This approach will allow you to minimize the risk of data loss and downtime of your production service when performing software upgrades. If necessary, you can rebuild your staging Virtual Server on demand so that you have a fresh installation to test on. If you need more information about setting up a Virtual Server for staging or testing, please contact eApps Sales.
IMPORTANT: PostgreSQL JDBC Driver 9.3 has an extensive list of new features and changes. See the Official PostgreSQL JDBC Driver 9.3 Release Notes for a list of changes that may cause issues when upgrading: http://jdbc.postgresql.org/documentation/93/index.html. Please read this document carefully to understand all the changes in the PostgreSQL JDBC Driver 9.3 release. Upgrading to this version may significantly impact the operation of your database and applications.
