Comment (by George Tantiras):
I cannot reproduce the issue using PostgreSQL-11.5.
Currently, Django Debug Toolbar reports the same number of queries when
using dal3, django-autocomplete or "no autocomplete".
However, there is a difference:
* When using dal3 or "no autocomplete" a query appears (it was not present
when I reported this issue):
{{{
DECLARE "_django_curs_140333492991744_3" NO SCROLL CURSOR WITH HOLD FOR
SELECT ••• FROM "inlines_master" WHERE "inlines_master"."id" IN (1)
}}}
* Django autocomplete reatains its behaviour, it does not produce the
above query rather than a proper SELECT as expected (the reason for
reporting this issue):
{{{
SELECT ••• FROM "inlines_master" WHERE "inlines_master"."id" IN (1)
}}}
Is there something right happening or something wrong?
