We are planning to upgrade a postgres 8.0 database to postgres 9.0 (Actually already done in Dev). The application is J2EE application with Hibernate. My question are
1) Is there a list of things that needs to be taken care while upgrading(known issues).
2) Do I need to upgrade JDBC driver when I upgrade to postgres9.0.
3) If we upgrade JDBC driver will we require to upgrade hibernate dialect?
4) Any other suggestions.
