Seems so.

recovery_connections was on by default and unanimous agreement until
recently and I don't want to change that now, just because a change
somewhere else appears to be forcing that but need not be so. It was
sensible to add a switch to turn HS off, but it should not be the
default, especially not one that requires a restart to enable a high
availability feature.

That is important in a feature that takes a while to "kick-in" and so
the user may patiently wait for it to come up and it never does.

I have no wish to repeat the situation that PostgreSQL requires a
restart to enable a feature, while other forks retain the ability to
enable the parameter without restart, as occurs with archive_mode, IIRC.

Perhaps we should not re-think wal_level if we've just moved the
parameter problem somewhere else?
