I am wondering if reindexing heavily used tables can have an impact on vacuum times. If it does, will the impact be noticeable the next time I vacuum? Please note that I am doing vacuum, not vacuum full.
I am on a FreeBSD 6.1 Release, Postgresql is 8.09
Currently I seeing a phenomenon where vacuum times go up beyond 1 hour. After I re-index 3 tables, heavily used, the vacuum times stay up for the next 3 daily vacuums and then come down to 30 to 40 minutes. I am trying to see if there is a relationship between re-indexinf and vacuum times. All other things remain the same. Which means the only change I am performing is re-indexing.
