Re: Critical failure of standby - Mailing list pgsql-general
Hey,
I understand that.
But a hot standby should always be ready to promote (given it originally caught up) right?
I think it's a moot point really as some sort of corruption has been introduced, the machines still won't wouldn't start after they could see the archive destination again.

Essentially this is a situation where DR is network separated from Prod - so I would expect the archive command to fail. I'll have to check the script it must not be passing the error back through to PostgreSQL.
This still shouldn't cause database corruption though right? - it's just not getting WALs.
if the slave database is asking for the WAL's, it needs them. if it needs them and can't get them, then it can't catch up and start.
