Correct.

The modules in contrib/dlz/modules are loaded at runtime. Since they're
dynamically linked, you don't have to link them into named at compile
time, so configure doesn't know about them.

The ones in contrib/dlz/drivers ones do need to be linked in at compile
time, so they still turn up as configure options even though they're
kinda obsolete now.

I expect them to go away in 9.17/9.18; the only reason they're still there
now is that a few of them support databases that we don't have modules for
(postgres, ODBC).
