+"""Regression test for index columns whose names require quoting (#6481).
+
+pg_get_indexdef() returns such a name quoted, so comparing it against
+pg_attribute.attname classified the column as an expression and the
+Properties panel showed nothing at all. The SQL now compares against
+quote_ident(attname), and the name is unquoted properly on the way out
+rather than by stripping quote characters, which mangled any name
