So running cluster on the words table (which is indexed with a seperate index
on each of the two fields) would probably decrease performance by getting rid
of one index without warning (the one NOT specified in the cluster command)?
How useful is clustering with pgsql when in a lot of situations systems have
enough memory to have the filesystem subsystem cache most or all index data?
Seek times shouldn't be an issue in such a situation, since the index doesn't
have to be read.
Just wondering,
