So you want to both (a) invent even more nonstandard syntax than we
already have, and (b) break as many traditional-Postgres applications
as you possibly can?
'transaction_timestamp' has no reason to live. It's not in the spec.
And AFAIK the behavior of now() has been well-defined since the
beginning of Postgres. If you want to change 'current_timestamp' to
conform to a rather debatable reading of the spec, then fine --- but
keep your hands off of now().
