PostgreSQL upgrade version 12 to 14
Oh it’s been a year since PostgreSQL 14 was released 1.
According to the PostgreSQL site, starting from version 10, the PostgreSQL Global Development Group (PGDG) releases a new major version approximately once a year 2. They also provide guidelines for the upgrading procedure 3, which includes the use of tools like pg_upgrade 4.
Now, let’s talk about my situation. I need to migrate my PostgreSQL database from version 12 to version 14.
