Bruce Momjian 613c6d26bd Fix incorrect error message reported for non-existent users 
Previously, lookups of non-existent user names could return "Success";
it will now return "User does not exist" by resetting errno.  This also
centralizes the user name lookup code in libpgport.

Report and analysis by Nicolas Marchildon;  patch by me
