@etr2460 I guess one could replace it though the position could change. This is a pattern I've used elsewhere where I simply increase the priority of the match by inserting it at the top of the list.

Oh also, should we consider forking sqlparse to:

  • Fix the issue preventing us from upgrading beyond 0.3.0
  • Let us fix other issues without cherry picking

cc @betodealmeida @villebro @amitmiran137 who might have thoughts here too

The change LGTM with some minor nits. It might also be worthwhile considering adding a unit test for this.

Could we add a TODO: here to remove when this is fixed upstream and also add a comment in setup.py where the version is pinned to remove this if it's been fixed?

@villebro I added a TODO. Note that sqlparse is pinned in setup.py here for other reasons—as already documented.
