I think the interesting bit is when you're at this point and the

notperformed at a regular enough interval, the slave is not truly a functioning standby. I think it's a different
problemdomain, probably best served by the existing pg_standby support? If the slave can be out of touch with the
masterfor an extended period of time, near real time logs provide no additional benefit over just shipping the archived
WALlogs and running the standby in continuous recovery mode?<br /><br /> Cheers,<br /> mark<br /><br /><pre
