No, the program itself simply takes an MD5 hash value and does a
brute-force search for a password that generates that MD5 string.

The comments at the top suggest sniffing a Postgres session startup
exchange in order to see the MD5 value that the user presents; which the
attacker would then give to this program. (Forget it if the session is
Unix-local rather than TCP, or if it's SSL-encrypted...)

This is certainly a theoretically possible attack against someone who
has no clue about security, but I don't put any stock in it as a
practical attack. For starters, if you are talking to your database
across a network that is open to hostile sniffers, you should definitely
be using SSL.
