Subject:   libpq++ uses fe_setauthsvc which is deprecated and results in an
 error on connection. This patch changes it to use PQconnectdb rather than
 {fe_setauthsvc,PQsetdb}. This still isn't the complete solution, as there is
 no provision for user,password in class PgEnv, but it does get rid of the
 error message. Tested with gcc version egcs-2.91.60 19981201 (egcs-1.1.1
 release) under NetBSD-1.3K/i386.

Cheers,

Patrick Welche
