Re: How to tune SQL performance of function based columns of a 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.

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?
