Hello Everyone!
We have a 9.2 pg cluster and we are in the process of rebuilding a master database in our staging environment. In order to achieve the latter goal, we are restoring our staging database using pg_basebackup against one of our production replicas.
pg_basebackup has completed and the staging database is configured in hot_standby mode, recovering from the WAL archive. The database has not reached the point were it can accept connections yet, still investing WAL files.
What we are not sure about is, can we attempt promoting the database as a master instance before it can accept connections ? We don´t care if the staging database is a few days behind the production environment, that is something acceptable in our use case, we just want to promote it as soon as we can.
Thanks in advance!
Best,
Martín
