Hello, we used to monitor the replication slot size on postgres 9.6.6 with the following query:
SELECT pg_xlog_location_diff(pg_current_xlog_location(), restart_lsn) FROM pg_replication_slots WHERE slot_name = 'SLOT NAME'; We are moving to postgres 10.4 and we saw the pg_xlog_location_diff is not there anymore. I know we can re-create it following this link : https://github.com/DataDog/integrations-core/issues/907 but, is there any better way to do it? Any replacement for that function on postgres 10? Thanks a lot, Nicola
