I'm finding these discussions very confusing to follow, sorry about
that.

We now have a parameter option that allows you to have row level
security in non-mandatory mode, which is good. But in order to get that
we need to build the server with a special configure option.

My previous objective was to remove the need for a configure option, so
we can enable row-level security in the default distribution of
Postgres. Are we going to enable that option in all normal distros? If
yes, why is it a configure option (at all)?
