Hi,
From the code I understood that when executing a query "normally", in
READ COMMITTED mode, we take a new snapshot for every query that comes
out of rewrite. But in an EXPLAIN ANALYZE, we only update the CID of
the snapshot taken when the EXPLAIN started.
Did I misunderstand the code? And if I didn't, why do we do this
differently?
