- Izkata 6y agoNot sure about each side of the UNION, but postgres can do parallel index scans for even simple criteria: https://www.postgresql.org/docs/10/parallel-plans.html#PARALLEL-SCANS https://www.postgresql.org/docs/10/parallel-plans.html#PARAL... Also the article says these tests were done on postgres 12.6
