With Django 1.6.2 I ran into the following stack trace:
{{{
...
close_old_connections()
File "/somewhere/virtualenv/local/lib/python2.7/site-
packages/django/db/__init__.py", line 94, in close_old_connections
conn.close_if_unusable_or_obsolete()
File "/somewhere/virtualenv/local/lib/python2.7/site-
packages/django/db/backends/__init__.py", line 462, in
close_if_unusable_or_obsolete
if self.is_usable():
File "/somewhere/virtualenv/local/lib/python2.7/site-
packages/django/db/backends/postgresql_psycopg2/base.py", line 192, in
is_usable
self.connection.cursor().execute("SELECT 1")
InterfaceError: connection already closed
<... at 0xac6ec0c> failed with InterfaceError
}}}
I see that `close_if_unusuable_or_obsolete` gracefully handles
`DatabaseError` exceptions. Shouldn't `InterfaceError` be caught as well?
FWIW -- I am invoking `close_old_connections` myself because I am making
heavy use of greenlets. I would like to call a Django method to close
connections if needed, without having to worry about exceptions like
these.
