Sorry I am not bumping this.  I meant to send this to the list as well.

I have been doing this for several years.  Since my database is small
and it takes little time to do a full vacuum.  I am doing the reindex
because I thought that was recommended after a full vacuum.

As the data has grown the system is slowing down.  Right now I am
looking at ways to improve performance without getting into the queries
themselves because I am swamped with new development.

Is doing the full vacuum and reindex hurting or helping anything?

Any other quick fixes that I can try?
