Re: Unable to start postgres instance.

Hi Douglas,

Appreciate your help.

'hot_standby = on' set up was already made but I restarted the server just in case, however I am still getting the same error.

But when I am attempting to reboot the database this is what I have noticed on the error logs

LOG: started streaming WAL from primary at 0/1B000000 on timeline 1
FATAL: could not receive data from WAL stream: ERROR: requested WAL segment 00000001000000000000001B has already been removed

LOG: received fast shutdown request
LOG: shutting down
LOG: database system is shut down

So, I am assuming the WAL files have already been deleted on the Master. Is there any setting on Master I can toggle in order to increase the expiry(retention policy) for the WAL files.

Thank You,
Sajan Gone

However its been on that from quite a long time. It would really appreciate if anyone could explain me on what is really going on.

It is doing exactly what it should. A standby is, by default, in permanent recovery mode. If you wish to be able to connect to it in this mode, you need to add 'hot_standby = on' to its postgresql.conf and restart the standby.
