[ squint... ] That makes no sense at all; it should certainly have
picked that index and not join_ids_join_id for a scan with a condition
on customer_id. What is the datatype of the customer_id column exactly?
(Actually, if you could show us the whole schema of both these tables,
such as their psql \d descriptions, that would be helpful.)
