Let me know if there's a better mailing list to ask this in.
I have a statistics collector that collects data from various postgres statistics tables, pg_stat_statements being one of them. This is done on an entire fleet of Postgres databases. From the collected data we record the timestamp of each collection in the query itself as extract(epoch from now()) as ts. What I'm seeing is that for the same query and query id, there are two rows with different statistics data at the same time. For example one row can have 2 calls while another can have 4. Anyone else run into this or have any idea why this can occur?
