Hi,
I'd
be grateful for some insight into the VACUUM functionality in 9.3. I
read through the documentation and searched around a bit but could not
find a definitive answer to this.
I'm setting up a weekly DB maintenance job for a 9.3 server.
Part of this will be a VACUUM FULL.
Is there any point in adding the ANALYZE option to the command ?
According to the 9.3 documentation, "VACUUM FULL
rewrites the entire contents of the table into a new disk file with no
extra space, allowing unused space to be returned to the operating
system.". If the table is completely recreated then do I need to
specifically ask for ANALYZE to happen or are the statistics updated
automatically as the rows are written to the new version of the table ?
Thanks,
