Well, so I need to do reindex frequentely in database? Is that right?
Or should I use cluster, as David said?
How frequently should I do this operation?

---------------------

Not necessarily.
If there is no table or index bloat, which you should be able to check first, - why bother?

Normally autovacuum does pretty good job even with default configuration parameters.
If not, you could start with adjusting autovacuum parameters.
And reindex only as a last resort, when your index size grows "uncontrollably".
