Re: [Bug] Logical Replication failing if the DateStyle is different in Publisher & Subscriber

You could make it a little less confusing by not insisting on a
space in the datestyle.  This should work fine:

        vals[i] = "-c datestyle=ISO,YMD -c intervalstyle=postgres extra_float_digits=3";

Also, I think some comments would be appropriate.

I don't see any value whatsoever in the more complicated version
of the patch.  It's just more code to maintain and more things
to go wrong.  And not only at our level, but the DBA's too.
What if the subscriber and publisher are of different PG versions
and have different ideas of the valid values of these settings?
