Thanks Tom. I found the relevant bit of code in the psql files. Looks like
it's just a simple loop that compares the error with the phrase
"fe_sendauth: no password supplied" and then prompts for the password and
tries again. Of course, if someone in the future decides to change the error
message, then the code gets broke. I doubt that's likely however.
