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,
