“Master PostgreSQL identifier is not matching with Slave PostgreSQL identifier” error while trying the PostgreSQL master-slave WAL replication

Question

I am trying the PostgreSQL-9.2 master to slave replication (through WAL log files) between a windows server (Master) and Windows machine (Slave).

Getting the error saying:

Master PostgreSQL identifier is not matching with Slave PostgreSQL identifier

However, when I try the Master-Slave replication between two machines, I can replicate the data between them.

How can I debug/fix this?

Answer 1

The slave has to be initialized with a physical backup of the master. Use pg_basebackup for the initial copy.
