#13630 closed Bug (fixed)

DatabaseOperations doesn't have same constructor with SQLITE and PostgreSQL backend

Description

Using sqlite3 backend on Django 1.2.1, the DatabaseOperations object is constructed without any parameter (no change from older versions).
Example:

from django.db import backend

backend.DatabaseOperations().quote_name(my_value)

But using postgresql_psycopg2 backend, the DatabaseOperations constructor need a connection as parameter :
Example:

from django.db import backend, connection

backend.DatabaseOperations(connection).quote_name(my_value)

So this is not possible to have a code working with all backends.

Actually, both PosgreSQL backends are the only ones accepting the connection parameter in their __init__ methods, Oracle, MySQL suffer from the same issue as reported by this ticket. We have an inconsistency here.

Fixed #13630 -- Made init methods of all DB backends' DatabaseOperations classes take a connection argument. Thanks calexium for the report.
