Re: Two entries with the same primary key

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

Hello Merlin,

we've resynced slave and now everything is OK, thanks you for help.

And only one last question, where to read about this bug, because my colleges  want to know, what happens.

Per some off-list conversation with Ivan, this is only happening on
the standby.  Ivan, what's the precise version of postgres you are
using?  When you first went to hs/sr?  I bet your clog files are out
of whack (and if so, probably upgrading to recent bugfix postgres and
standby resync is the correct course of action).
