Re: seeing lag in postgresql replication

Hi, What version of postgresql do you have ? Do you use streaming replcation or a different tool like repmgr or pgpool or something else ? What are all the configurations for you wals(the parameters depends on your version..) ? Do you see any errors or warnings in the server log ? Regards, Mariel.
