Hello,
I'm planning to cluster a few large tables in our database but I'm
unable to find any recommendations/documentation on best practices --
Mainly, whether it's better to use an index which has a higher idx_scan
value, a higher idx_tup_read value, or the higest idx_tup_fetch value.
Can anyone point me to docs which explain this better?

TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match
