A quick look in the pg_passwd sources indeed shows some hardwired limits
on both username and password length. This is bogus. Anyone want to
contribute a patch?
For the record, the max username length should be NAMEDATALEN-1, and
the password field in pg_shadow is 'text', so it should be happy to
take any password that you're willing to type ;-). However, crypt
password processing depends on crypt(3), which more than likely ignores
characters beyond the eighth on most platforms.
