Hi,
when switching to postgres 14 (from 11) I'm having some slow queries because of inlining of CTE's.
I know I can get the same result as with PG11 when adding MATERIALIZED to the cte, but the same application also needs to be able to run on older postgres versions, so that is a no-go.
Is there any other way that I can have materialized cte's in PG14 while still be compatible with older PG versions?
Much appreciated,
The usual anti-inlining hack is to add an “offset 0” to the query. Haven’t tried it in 14 myself though.
