<command>VACUUM</> once a day at a low-usage time of day, supplemented
by more frequent vacuuming of heavily-updated tables if necessary.
(If you have multiple databases in a cluster, don't forget to
- vacuum each one; the <filename>vacuumdb</> script may be helpful.)
+ vacuum each one; the program <filename>vacuumdb</> may be helpful.)
Use plain <command>VACUUM</>, not <command>VACUUM FULL</>, for routine
vacuuming for space recovery.
