It's pretty simple. to_char(..., 'MI "min"'). It's already supported by
to_char() format parser.
I think to_char(interval) should be support split interval to more
items, like:
to_char(INTERVAL '1d 3h 65s', 'HHh MIm SSs') ---> '27h 1m 5s'
Well, I'm going to check how difficult will be implement correct to_char
(interval).
