column? Is constraint_exclusion enabled and working for that?
It looks like test.prod.fact_624 is being read using index in under 1sec, and
the rest using seq scan, taking 5-10sec.
So what are the table+index definitions of the parent and childs (say fact_624
and 631).
Have the child tables been recently ANALYZE ?
Also, have you manually ANALYZE the parent table?
