I want to reduce the number of queries I'm making to my postgres database.

Currently I have this

```
select * from token_balances where asset_id = '36f813e4-403a-4246-a405-8efc0cbde76a' AND tick < yesterday ORDER BY tick DESC LIMIT 1;
select * from token_balances where asset_id = '36f813e4-403a-4246-a405-8efc0cbde76a' AND tick < last_week ORDER BY tick DESC LIMIT 1;

```

Is there some way I can make this into one query. Or is there even any need to reduce it?

Thanks
