We run heaps of PHP based sites on this codebase. If you want to
upgrade to 7.4.1, Oliver Elphick (the Debian maintainer) has produced
packages for Woody that we also use in some situations:

deb http://people.debian.org/~elphick/debian/ stable main

It seems most likely to me that your webserver is attempting to
authenticate as www-data using 127.0.0.1 (rather than 'local' - i.e. no
host spec in pg_connect) and that you are not allowing that in your
pg_hba.conf, but the notes below do not give a lot of information to
work from.

Perhaps send the auth.php (with usernames / passwords munged), a "select
* from pg_user" (ditto)
