./pg_ctl promote -D /usr/edb/as12/data

Once the command is executed, it verifies any files available in the pg_wal folder, replays them, and then starts as a master node. It does not try to connect to the (old) master server, and hence the promotion is very fast.

Percona Operator for PostgreSQL v2.6.0 adds PostgreSQL 17 support. Since pg_tde comes pre-installed in Percona's official PostgreSQL 17 images, you can encrypt PostgreSQL data at rest.
