Yes. See date_trunc function. Of course this truncates down to the
specified unit. If you want to round up/down to the nearest minute I
suppose you could just add '30 seconds'::interval before truncating.

select
now(),
date_trunc('minute', now()),
date_trunc('minute', now()+'30 seconds'::interval);
