Take a look at this explain

I maybe missing it, but I do not see the actual query.

The final number of records is very small but PG is starting out with a
massive number of records and then filtering most of them out.

I don't want to really force pg to always use the same index because in
some cases this strategy would win but I am wondering if there is
anything I need to do in order to get the planner to make better decisions.

I already did an analyze on the table.
