I've read a lot where people recommend using VACUUM FULL to free up disk space, especially after many updates/inserts.
But does a regular VACUUM (or VACUUM ANALYSE) ever free up any space?
24/7 production databases cannot be locked for long periods of time to run VACUUM FULL, but I do not want data files growing indefinitely (any more than they need to) so I hope the routine VACCUM ANALYSE will take care of this.
My pg is version 7.2.x but the question can apply to newer versions as well if the functionality has changed.
Regards, Chris.
