Postgresql Streaming Replication on Windows failover
Pergunta
Hello i have setup streaming replication using PostgreSQL 11 on Windows working OK. How can i manually use the replica ( it is hot_standby=on ) in case Master fails ? What are the steps i have to perform to the replica ?
Solução
Like the documentation says, there are three ways to promote a standby server:
run
pg_ctl promote
on the command line.create a trigger file (if you have configured the standby server accordingly).
from v12 on, you can also execute
SELECT pg_promote();
