That's an argument for why Postgres maybe shouldn't print times with "m" for
minutes -- though I for one would prefer it. Or why it might not be a
particularly good idea for a sysadmin to use "m" given the choice.

But to argue that Postgres should refuse "m" when presented with it you would
have to say there's a substantial chance that the user didn't mean minutes and
that there was a risk Postgres would do something bad that outweighs giving
users who do want minutes getting what they want.

Frankly, I think I see "m" as an abbreviation for minutes *more* often than
"min" anyways. I see times written as 2h30m quite frequently and then there's
precedent like this: 

$ time echo

real	0m0.000s
user	0m0.000s
sys	0m0.000s
