Message-ID: <[email protected]> (raw)
pg_plan_advice: DO_NOT_SCAN is a simple tag, not a generic one.
Generic tags allow sublists, e.g. MERGE_JOIN((x y)), but simple
tags do not, e.g. SEQ_SCAN(x) is valid but SEQ_SCAN((x)) is not.
DO_NOT_SCAN was intended to be simple tag, but was accidentally
implemented as a generic one. This could result in assertion
failures. Repair.
