Hello Sterpu,

 

First, please run vaccum for your Postgresql DB.

 

No rows returned from your query. Could you double check your query criteria.

 

After that could you send explain analyze again .

Hello

 

I'm on a PostgreSQL 12.1 and I just restored a database from a backup.

When I run a query I get a big execution time: 5.482 ms

After running EXPLAIN ANALYZE I can see that the "Planning Time: 5165.742 ms" and the "Execution Time: 6.244 ms".

The database is new(no need to vacuum) and i'm the only one connected to it. I use a single partition on the harddrive.

I also tried this on a postgresql 9.5 and the result was the same.

I'm not sure what to do to improve this situation.

The query and the explain is attached.

 

Thank you

 

Have you run the ANALYZE command to update your DB statistics?
