In initdb, don't bother trying max_connections = 10.

Browse Source 
The server won't actually start with that setting anymore, not since
we raised the default max_wal_senders to 10.  Per discussion, we don't
wish to back down on that default, so instead raise the effective floor
for max_connections (to 20).  It's still possible to configure a smaller
setting manually, but initdb won't set it that way.

Since that change happened in v10, back-patch to v10.
