Hi. I have two existing tables, A and B. A has a 'varchar(1000)' field
and B has a 'text' field, each with btree indexes defined. When I do a
join between these, on this field, it seems to a hash join, as opposed
to using the indexes, as I might expect (I'm no postgres expert, btw).
My question is: if I changed both fields to be text or varchar(1000)
then would the index be used?
Ta,
