Streaming Replication between PostGreSQL 9.2.2 on Red Hat and PostGreSQL 9.2.24 on Debian

Hi there,

I'm trying to configure streaming replication between a Red Hat server
running PostGreSQL 9.2.2 and a Debian server running PostGreSQL 9.2.24 with
Hot Standby enabled.

While the base backup works fine using *pg_basebackup*, I get the following
errors with hot standby enabled on the Debian slave when starting
PostGreSQL:
*WARNING: WAL was generated with wal_level=minimal, data may be missing*
*HINT: This happens if you temporarily set wal_level=minimal without
taking a new base backup.*
*FATAL: hot standby is not possible because wal_level was not set to
"hot_standby" on the master server*
*HINT: Either set wal_level to "hot_standby" on the master, or turn off
hot_standby here*

If I turn Hot Standby off on the Debian Slave I get the following errors:
*FATAL: database system identifier differs between the primary and standby*
*DETAIL: The primary's identifier is 5940475598986796885, the standby's
identifier is 6557962695089036503.*

Configuring streaming replication with Hot Standby enabled locally on the
Red Hat server works like a charm, and I've thus concluded that the issues
must be one of the following:
- PostGreSQL's minor version differs between the 2 servers
- The two servers are running different operating systems

Any insight or guidance as to achieve this scenario would be greatly
appreciated.

Cheers
Jona
