Comment (by Bálint Balina):
Ok, I have super simple solution, but I would like to pre check if this is
a possible way to go. Can we use lower case table aliases?
I have applied the following monkeypatch, and everything works fine for my
case:
{{{
Query.alias_prefix = 't'
Query.subq_aliases = frozenset(['t'])
def bump_prefix(self, outer_query):
...
alphabet = ascii_lowercase
...
Query.bump_prefix = bump_prefix
}}}
