I am trying to measure the time taken for a number of queries using \timing . All queries on my table other than the first one are pretty fast. This is likely due to caching. Is there any way to clear the internal cache of Postgres. Should I be worried about the entire OS cache also?
restarting postgres ought to do it.however, also note that your OS's disk cache plays a big role, and generally the only way to flush that is to reboot and/or do a lot of other random IO.
