I assume that (a) after a trac upgrade from a version depending on pypgsql to one not needing it I had pypgsql depcleaned out. However, reemerging trac only with psycopg installed didn't make it function again. My config is fastcgi trac on vhost, using www-apps/trac-0.11.2, dev-lang/python-2.5.4-r2, www-apache/mod_fcgid-2.2, www-servers/apache-2.2.11 on a hardened gentoo server. Reproducible: Always Steps to Reproduce: 1.Install trac using posgresql as backend (perhaps try an older version depending on pypgsql and upgrade to latest?) 2.Remove pypgsql (emerge -C or a perhaps a depclean) 3.Try use trac Actual Results: Traceback (most recent call last): File "/usr/lib/python2.5/site-packages/trac/web/api.py", line 367, in send_error 'text/html') File "/usr/lib/python2.5/site-packages/trac/web/chrome.py", line 688, in render_template data = self.populate_data(req, data) File "/usr/lib/python2.5/site-packages/trac/web/chrome.py", line 596, in populate_data d['chrome'].update(req.chrome) File "/usr/lib/python2.5/site-packages/trac/web/api.py", line 194, in __getattr__ value = self.callbacks[name](self) File "/usr/lib/python2.5/site-packages/trac/web/chrome.py", line 464, in prepare_request for category, name, text in contributor.get_navigation_items(req): File "/usr/lib/python2.5/site-packages/trac/ticket/web_ui.py", line 162, in get_navigation_items if 'TICKET_CREATE' in req.perm: File "/usr/lib/python2.5/site-packages/trac/web/api.py", line 194, in __getattr__ value = self.callbacks[name](self) File "/usr/lib/python2.5/site-packages/trac/web/main.py", line 261, in _get_perm return PermissionCache(self.env, self.authenticate(req)) File "/usr/lib/python2.5/site-packages/trac/web/main.py", line 132, in authenticate authname = authenticator.authenticate(req) File "/usr/lib/python2.5/site-packages/trac/web/auth.py", line 70, in authenticate authname = self._get_name_for_cookie(req, req.incookie['trac_auth']) File "/usr/lib/python2.5/site-packages/trac/web/auth.py", line 184, in _get_name_for_cookie db = self.env.get_db_cnx() File "/usr/lib/python2.5/site-packages/trac/env.py", line 264, in get_db_cnx return DatabaseManager(self).get_connection() File "/usr/lib/python2.5/site-packages/trac/db/api.py", line 76, in get_connection return self._cnx_pool.get_cnx(self.timeout or None) File "/usr/lib/python2.5/site-packages/trac/db/pool.py", line 174, in get_cnx return _backend.get_cnx(self._connector, self._kwargs, timeout) File "/usr/lib/python2.5/site-packages/trac/db/pool.py", line 107, in get_cnx cnx = connector.get_connection(**kwargs) File "/usr/lib/python2.5/site-packages/trac/db/postgres_backend.py", line 46, in get_connection cnx = PostgreSQLConnection(path, user, password, host, port, params) File "/usr/lib/python2.5/site-packages/trac/db/postgres_backend.py", line 118, in __init__ from pyPgSQL import PgSQL ImportError: No module named pyPgSQL
Has this happened with 0.11.5 as well? It looks like Trac is trying psycopg2 first, and only falling back to PyPgSQL if that fails.

Cool, I'll close this bug.
