Support for postgresql cluster

[NgariNdungu]

I have setup the sql pump pointed to a postgresql cluster which works well until there is a database fail-over.
The pump seems to retain the old connection resulting in error;
ERROR: cannot execute INSERT in a read-only transaction (SQLSTATE 25006)

The connection_string am using is;
'host=tyk-postgres-cluster.tyk.svc.cluster.local port=5432 user=tyk_analytics_owner_user dbname=tyk_analytics password=$(DB_OWNER_PASSWORD)'
Where the host points to the cluster service for the master nodes.
Restarting the pump usually fixes the issue.

Does tyk-pump support pushing analytics to a postgresql cluster?
