In general terms synchronous replication moves at the speed of the connection
between the primary and standby or does not occur if the standby can not be
found. So what is the state of the connection between the primary and standby?
Connection is working fine between primary and standby, ping is working fine and wal archive file transfer is working without any issues.
I tried CREATE TABLE and CREATE DATABASE, both were hanging.
Apart from regular streaming replication settings, I did the following on primary to enable synchronous replication -
synchronous_standby_names='*'
Commands started hanging after that. Is there anything else i need to do.
Thanks
