Oh, I misread the code, now that you mention it. libpq reads the
password up to the first unescaped colon. So one could write:

10.143.170.206:5432:*:11026270:Blarge: # Host name: fubar

Note the colon right after "Blarge". But that will very likely clash
with fields that may be added in the future.
