Updated the PR to change the warning to be a comment instead of printing it to stderr

I actually found a solution to this in SQLite3 through PRAGMA keyword but since PRAGMA is a SQLite3 specific command so my PR didn't passed the Jenkins tests https://github.com/django/django/pull/15683. If you could provide any suggestions cause if we use get_constraint method to fetch the primary key it only takes the first column as primary key and gives no info if there were other primary-key columns. Also I tried the changes given in PR https://github.com/django/django/pull/13736 but they didn't work.

inspectdbis meant as a shortcut, not as definitive model generation. I would rather add a comment to the field'snoteslike we do in other cases. Raising a warning can be really annoying when you try to inspect a legacy database.
