There are range specific functions for this:
select daterange(now()::date, now()::date, '[]')

Marc, thanks - indeed it's right there in 8.17.6! As you might suspect,
I'm rushing through things more than I'd care to, so I'm grateful for this
list and the dose of sanity it provides :)
Cheers,
John

Seems I'm missing a trick trying to get rangetypes working:
No problem building the string:
select concat('''[', now()::date, ',', now()::date, ']''') testrange;
testrange
---------------------------
'[2015-02-26,2015-02-26]'
(1 row)
Bombed-out trying to turn this into a daterange:
postgres=# select concat('''[', now()::date, ',', now()::date,
']''')::daterange testrange;
ERROR: malformed range literal: "'[2015-02-26,2015-02-26]'"
DETAIL: Missing left parenthesis or bracket.
Is there a specific casting I need to apply in order to render a literal
daterange from parameterized range elements?

Sorry - too quick to post, I realize there was no need to wrap the
expression in extra quotes:
postgres=# select concat('[', now()::date, ',', now()::date,
']')::daterange testrange;
testrange
