The reason I added it is that usually people think of the PG syntax as
'1 hour 30 seconds'. The '1:30' is a kind of subtle because both PG and
ANSI support that syntax and we need to handle that. The tricky part is
that we can't say by looking at '1:30' whether it is PG or ANSI, and
that will affect how we deal with the clause after it.
