Yes.
This is what I do.
1. Vacuum full
2. Reindex force
This is done ever night
My users complained about a report being slow.
I grabbed a dump and restored it to my development machine.
The query worked just fine, but not on the production server.
I did a vacuum full and then reran the query. Now it performs just as
slow as on the production machine. That is the only change I made.
I am in the process of trying to figure out the EXPLAIN ANALYZE for
both queries, but I have never had to read this output and I am
unfamiliar with how to find the problem. I will post both here and
maybe someone can help me out.

I have a query that takes 2 sec if I run it from a freshly restored

If you run it a second time after the vacuum full?
