I have heard that postgres will not use an index unless the field has a not null constraint on it. Is that true?
I have never heard that. There are some oddities with using an Index. For example,
if you are using a bigint you need to '' the value or if you are using an aggregrate function (mix/max)
you have to specify a where clause but I have not heard the one you have mentioned.
Anybody else?
Sincerely,
Joshua Drake
