Downgrading postgres?

[eisen009]

I didn't realize the newer postgres versions weren't supported and my active db on PT4 is with postgres 9.5. Just downloaded 9.3 but not clear how to create a new db with 9.3? It seemed like things were working fine with 9.5 other than the warning message that comes up every time I start PT4. Do I need to create a new db with 9.3? Or is it fine to stick with 9.5? If I have to create a new one, how do I do that? Not obvious to me.

Thanks! Lara

If you have been using PostgreSQL v9.4 or later without any problems then you can continue to use a later version if you wish to do so but that does not necessarily mean there won't be a problem with that version further down the line. If you choose to change versions then PostgreSQL v9.3 won't be able to access your PostgreSQL v9.5 database so you would have to create a new database anyway and reimport your hands. PostgreSQL does change some functionality between major versions and while you could use the PokerTracker backup/restore functions to transfer your data I would only recommend that if you were upgrading PostgreSQL and not going the other way. If you need to locate your hands by default PokerTracker 4 moves your processed hand histories to your \PokerTracker 4\Processed folder which you can access via the "File -> Open User Data Folder" option.

Guide: Processed Files

If you do not have all the hands you need you can also export hands from the existing database (and don't forget to export your notes if you want them via "Database -> Notes"). When you are ready you can then follow this tutorial to reinstall PostgreSQL.
