Yes !
you've got it... Now, postgres uses "Index Scan".

"id" is an int8. I didn't knew that it has to be quoted in order to be
interpreted into something else than an int4.

IMO it's a good idea to quote all numerics regardless of type in postgres. as a side effect, it will allow the planer
tomake smarter choices for int8.
