Hello, we currently have 9.4 hot_standby master-slave pair. Going forward, we can keep only one server. How can I convert the system properly?
These are some snippets from master postgresql.conf file:
==================================
wal_level = hot_standby # minimal, archive, hot_standby, or logical
# (change requires restart)
checkpoint_segments = 16
wal_keep_segments = 512
max_wal_senders = 16 # max number of walsender processes
# (change requires restart)
max_replication_slots = 12 # max number of replication slots
===================================
Is it enough if I do the following:
1) backup all dbs on master
2) shutdown both servers
3) update max_replication_slots=0 in postgresql.conf on master
4) update wal_level = minimal in postgresql.conf on master
4) start master
Do I need to do anything else? Thank you for your help
