Arch Linux

Description:
After upgrading to postgresql 12.5-1, the postgresql.service no longer starts:

According to the latest package commit - https://github.com/archlinux/svntogit-packages/commit/19b0f262e7f1ead2c0ec03d001c20d83fcfefd62 - the postgresql-check-db-dir script checks if the database major version is now 13, but the package contains PostgreSQL 12. Reinitializing the database still creates a 12.x database. Version change in the script should be reverted.

Steps to reproduce:
- Upgrade the postgresql package to 12.5-1
- Initialize and set up your database according to the wiki
- systemctl start postgresql
