Suppose I have to check against 100,000 uids for a single update statement - my code currently will break this into 1000-uid chunks:

```
[...] WHERE UID IN (..., '998', '999', '1000') 
OR UID IN ('1001', '1002', ...) 
OR (..., etc., ...)

```

Is there a maximum number of OR clauses you can have? I.e., in my example above, it would generate 100 OR clauses of 1000 IN clauses each.
