Unfortunately neither A nor B apply anymore.

However, since the patches can still be read through I wonder if Robert
or Andres would care to opine on whether A or B is better now that they
can see the full implementation?

For my 2c I'm happy with XLogInsertExtended() since it seems to be a
rare use case where flags are required. This can always be refactored
in the future if/when the use of flags spreads.

I think it would be good to make a decision on this before asking
Michael to rebase.
