It do understand that currently PG replans with $1, $2 and uses
default selectivities for that.

What I am asking is to make PG aware of "previously used bind values",
so it would calculate proper selectivities for $1, $2.

PS. It is not the first time the problem bites me, so I hand-crafted a testcase.
