[ CC'ing to hackers because this is getting into code problems. ]
Here's another inconsistency that Tatsuo found:
test=> create table ff (x time default 'current_timestamp');
ERROR: Bad time external representation 'current_timestamp'
test=> create table ff (x time default 'current');
ERROR: Bad time external representation 'current'
test=> create table ff (x time default 'now');
CREATE
test=> select current_timestamp;

You can default a time to now, but not to current or current_timestamp.
I believe this is happening because current is implemented as special
timezones in datetime.c and timestamp.c, and current_timestamp is
implemented in gram.y, while 'now' is a function.
Anyway, looks like confusion that should be fixed.
