PostgreSQL Database Error

[PolacoGoyeneche]

Hello. I'm having this error and I don't know how to fix it. I've tried reinstalling both PokerTracker and PostgreSQL with their various updates. What should I do?

You have installed PostgreSQL v17 which isn't supported. Please uninstall it and install PostgreSQL v16 instead:

Guide: Installing PostgreSQL

Bear in mind if you want to connect to and use previous databases then you would need to still have the original PostgreSQL 'data' folder and install the same version of PostgreSQL that was being used for those databases if it wasn't v16 otherwise you will need to create a new database or restore from a database backup if you have one.
