Re: BDR Monitoring, missing pg_stat_logical_decoding view

Thank you, that was helpful.

In the pg_replication_slots view, I see that xmin is always NULL, is that expected? I'm not sure how to measure the BDR update latency without this xmin value.

If I run pg_get_transaction_committime(catalog_xmin), sometimes I get what looks like a default time stamp of 1999-12-31 16:00:00-08, is that expected?

Thanks,
Steve Boyle

It has been renamed since - it's part of postgresql 9.4 and named pg_replication_slots. It seems most of the page refers to it by the correct name, just a subsection doesn't... Sorry for that.
