Hi everyone,
I’m using LIMIT offset with DB view. Looks like query planner is applying the LIMIT for DB view at the end after processing all rows.
When running same SQL that was used to create the DB view, LIMIT is applied earlier so the query is much faster.

In both tests LIMIT was 100 with offset = 0.
Is there any way to force DB view to apply limit earlier?
Thanks,
Raj
