Re: [Postgres-xc-developers] GTM standby bugs

[鈴木 幸市 <ko...@in...>]

Andrei;

It's wonderful to have these fixes, especially sequence issues, which is already in the bug track.

Error messages need some more thought, I think.   Node registration will be useful in the future.   Disabling this could be a quick fix but I think we should keep this code.

Thank you very much;

The problem disappears if I remove file register.node from the GTM master data directory. Before I start looking into details, why GTM needs to save information about running nodes? Cluster may be shut down for reconfiguration and information in register.node may be out of date. At the same time when nodes connect to GTM they deliver actual information.
