Minor versions of PostgreSQL (e.g., from PostgreSQL 13 to PostgreSQL 13.2) are always backward compatible with the major version. That means that if you upgrade your production database, it is unlikely that anything is going to break due to the upgrade. However, major versions of PostgreSQL are not backward compatible.

Already here we can see that Postgres 14 does much better in the initial data load. As you can see, the throughput of Postgres 14 at 5000 active connections is about 20% higher. At 10,000 active connections the improvement is 50% over Postgres 13, and at lower connection counts you can also see consistent improvements.

How to upgrade Postgres from 13 to 14

On Red Hat Enterprise Linux and derivatives using yum

  1. Install Percona Distribution for PostgreSQL 14 packages.
  2. Set up Percona Distribution for PostgreSQL 14 cluster.
  3. Log is as the postgres user.
  4. Set up locale settings.
  5. Initialize cluster with the new data directory.
  6. Stop the postgresql 13 service.

Until PostgreSQL 14 only the superuser(s) were allowed to execute CHECKPOINT commands. Starting with PostgreSQL 15 there is a new role called pg_checkpointer. Once you grant that role to an user, it is able to execute CHECKPOINT commands. You are now connected to database "postgres" as user "checky" .Let's do some benchmarks to see how the merge algorithm change affects the performance of PostgreSQL 15. Figure 4 above shows us that PostgreSQL 15 performs much better than PostgreSQL 14 for large sorts with very small values of work_mem . As the work_mem setting is increased, the performance gap decreases.
