Postgres SSL error: decryption failed or bad record mac

There is an error running Wooey on a Postgres database backend (and using the same backend for celery):

[2015-08-12 13:19:33,616: ERROR/MainProcess] Unrecoverable error: OperationalError('SSL error: decryption failed or bad record mac\n',)
Traceback (most recent call last):
  File "/usr/local/lib/python3.4/dist-packages/django/db/backends/utils.py", line 64, in execute
    return self.cursor.execute(sql, params)
psycopg2.OperationalError: SSL error: decryption failed or bad record mac

This SO post mentions the error with another library and the solution suggests opening the DB connection within the job.The Heroku Postgres documentation makes it a bit clearer:

The Postgres connection is shared between more than one process or thread. Typical offenders are Resque workers or Unicorn. Be sure to correctly establish the PG connection after the fork or thread has initialized to resolve this issue.

I’m experiencing this too, inside of Flask

I had the same problem with Flask + uSWGI + psycopg2. I solved it by inserting the line:

lazy-apps = true

in the file uswgi.ini.
