After upgrading to TG-2.2 I noticed the following error (see below) when browsing pages in admin/ controller like: admin/groups/. The error paper only when I am using real-db (PostgreSQL) and does not appear when I am using sqlite.
Any idea how to fix this?
Thanks,
Erni.

Perhaps you can share your shema/models?, I have a related problem
that is triggered by a specific model, not sure what it is, seems like
datetime fields, but I will try to go deep into this afternoon and
would be helpful to check your problems at once (as they seem
related).

This seems to be a problem going back to tgext.crud, seems like the
special paginator that tgext.crud uses does not follow the __len__
protocol strictly and python raises this error.
Normally the length of the list or collection is given as an int, but
I imagine psycopg2 returns a long somewhere and the class
SmartPaginationCollection does not check this and just uses it as is.
I will fill a bug later on github, I already have a working patch but
perhaps this needs some fixing deeper on.

Carlos Daniel Ruvalcaba Valenzuela
