New version to corect errors like:
Error: Ns_PgExec: result status: 7 message: ERROR: function
poll__new("unknown", "unknown", "unknown", timestamp with time zone, timestamp with time zone, "unknown", "unknown", "unknown", "unknown") does not exist ....
when try to create a new poll. Just correct timestamptz data type in datamodel.
