35240	Django doesn't set Postgres timezone to UTC when using psycopg3	Fabi	nobody	"Configuration uses `USE_TZ=True` and database defaults to `America/New_York`. I would expect the connection then being set to UTC, but it is not changed:
{{{
In [4]: connections[""default""].cursor().connection.info.timezone
Out[4]: zoneinfo.ZoneInfo(key='America/New_York')
}}}

The wrapper and the psycopg3 timezone adapter both think its UTC though:
{{{
In [5]: connections[""default""].timezone
Out[5]: datetime.timezone.utc

In [6]: connections[""default""].cursor().connection.adapters.get_loader(TIMESTAMPTZ_OID, Format.TEXT).timezone
Out[6]: datetime.timezone.utc
}}}

Looking at the code I think the problem is that the adapter gets initialized with `self.timezone` which then gets compared with `self.timezone` later again, resulting in a no-op:
