full is something you run when things have gone wrong (i.e. not enough

your indexes.
It's far better to keep track of bloat and run vacuum full, if at all,
by hand, and only when needed. Running it regularly with no
reindexing often results in index bloat which makes the database
slower not faster.
I've been trying to research this issue. I can't really find
documentation that defines when to 'vacuum full.' That is other then
this posting on the list and the following from the man page:
'The FULL option is not recommended for routine use, but may be useful
in special cases. An example is when you have deleted most of the rows
in a table and would like the table to physically shrink to occupy less
disk space. VACUUM FULL will usually shrink the table more than a plain
VACUUM would.'
So, I'm wondering if anyone can point me to more specific information as
to when, if ever, you should 'vacuum full?'
The more research I do, the more it appears that you should only 'vacuum
full' when you run into space issues.
