I get this warning when trying to fetch data for a postgres db. Does this indicate a real issue? Thanks
Well it means the statistics for the table are out of touch with reality. The database will not fall over, but your queries against the table will be using stale statistics when the query planner sets up the query.
Running VACUUM recommended The estimated rowcount on the table "recorder" deviates significantly from the actual rowcount. You should run VACUUM ANALYZE on this table.
I would take the suggestion, or you can wait till autovacuum hits the table.
AFAIK, this part of the code in pgAdmin hasn't been touched since quite a few years. You shouldn't rely on it to know which tables need a VACUUM or an ANALYZE.
