Sure.  The point is that these are (RDBMS dependent, BTW) details
which can be arranged later (depending on whether the overload
due to reloads is an issue or not, which also depends on the scenario).
The first issue is to have syncrepl working with a producer that is not
syncrepl-aware (e.g. doesn't recognize the control).
