Make it a Materialized View with storage and you can index on a column. You can index a MV unlike a regular view.

Hi Ron,
I have analyzed and vacuumed following 2 tables which are used by the views.
TEK_INSPECTION_LIST_MCM
TEST_PART_DETAILS_ALL_MCM_MID
I am still seeing unacceptable response time.
Is there any other way to tune a SQL which is referring a view?
Thanks,
Sarwar

Postgresql does auto-vacuum and auto-analyze, so the table might have been analyzed and vacuumed.
Table pg_stat_user_tables records the last time that user tables were vacuumed and analyzed.

This is Pg 13.
It is running on Aws / Rds.
I am not doing any Vacuum/ Analyze manually.
Thanks,

Hello,
I am working on SQL performance issue.
1. What PG version?
2. When did you last VACUUM and ANALYZE the base tables?
