Hmm. I can see how a linefeed in a password would create a problem (it
breaks the line-oriented formatting of the pg_pwd file). However, I
can't reproduce a postmaster crash here. Either I'm not testing the
right combination of circumstances, or current sources are more robust
about this than 7.1. That's not unlikely given that Bruce rewrote the
password-file-parsing code a couple months ago.
In any case it seems like it'd be a good idea to forbid nonprinting
characters in passwords. Comments anyone?
