What about using
WHERE f BETWEEN '2012-04-23 00:00:00' AND '2012-04-24 00:00:00'?

As PostgreSQL stores timestamps with a fractional part, does it mean that
WHERE f BETWEEN '2012-04-23 00:00:00' AND '2012-04-23 23:59:59' might miss
records with values of f equal to 23:59:59.1234 or so?
yes, it does. BETWEEN doesn't work well for timestamps.
you have to do it the long way
f >= '2012-04-23 00:00:00' AND f < '2012-04-24 00:00:00'
