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.

Hello,

 

I am working on SQL performance issue.


1. What PG version?
2. When did you last VACUUM and ANALYZE the base tables?
