Some UNION queries can start with "(", causing it to not be
classified as a SELECT query, and consequently the select and
explain buttons are missing on the SQL panel.

How come this is only valid for postgres? I feel like the other db drivers should also pass this test.

From a quick look at the Django code, this can only happen if the DB backend has supports_slicing_ordering_in_compound = True. But I see now it is more widely supported than I thought. Shall I rather use
@unittest.skipUnless(connection.vendor != "sqlite", "...")?

I'm not sure why the skipUnless is even necessary? The test should pass on all database engines anyway, or not?
