I have now PT3 with PostgreSql 8.3.9. I upgrade my PT3 license to PT4.
Before I install PT4 should I install latest PostgreSQL software? What is the latest supported PostgreSQL version? 9.2.1 or only 9.0.10?
How can I migrate PT3 database (8.3.9) to PT4(9.2.1 or 9.0.10)? Does the PT4-Setup Assistant do it?
