Ok, so installing psycopg2 did make web2py use it instead of pg8000. And I
stopped getting the error I was seeing before.
However, when trying to start the scheduler, I get another error, which
from what I see comes from the line right after the one generating the
previous error:
web2py.scheduler.localhost#20734 - ERROR - Error retrieving status
scheduler_worker
localhost#20734
Traceback (most recent call last):
File "/home/www-data/web2py/gluon/scheduler.py", line 963, in
send_heartbeat

File "/home/www-data/web2py/gluon/dal.py", line 9293, in insert
ret = self._db._adapter.insert(self, self._listify(fields))

Up to here, I am just trying to start the scheduler. I don't even have any
tasks added to the queue yet. There seems to be a problem with the
worker_stats Storage object, it seems it is not being converted to JSON but
just passed with quotes around it. But again, this seems to be inside
web2py, not anyting that I am doing in my code. Do you have any clues on
what the issue may be this time, and what I could do about it? Again, my
goal so far is just to be able to start the task scheduler on a PostgreSQL
database....
Thanks again,
Sebastian
