I believe that we should keep them as float8, on the basis that a user
is more likely to generalise from total_time's format (when writing a
script to query the view of whatever) than from that of
pg_stat_database.
A part of me would like to change the view definitions so that all the
columns are strongly typed (i.e. all these values would be intervals).
I realise that that isn't practical though.
