In previous versions the max size of a domain was bounded by psycopg
memory limits. With the new SQL formatting mechanism the limit is bound
by the maximum recursion limit in Python side. The purpose of this patch
is to restore previous behavior.
In 16.0:
```
>>> def make_dom(N):
... return [*('|' for x in range(N-1)), *(('login', '=', 'admin') for x in range(N))]
...
>>> u.search(make_dom(9984))
res.users(2,)
>>> u.search(make_dom(9985))
Traceback (most recent call last):
File "<input>", line 1, in <module>
u.search(make_dom(9985))
File "/home/odoo/src/odoo/16.0/odoo/models.py", line 1520, in search
return res if count else self.browse(res)
File "/home/odoo/src/odoo/16.0/odoo/models.py", line 5140, in browse
if not ids:
File "/home/odoo/src/odoo/16.0/odoo/tools/query.py", line 217, in __bool__
return bool(self._result)
File "/home/odoo/src/odoo/16.0/odoo/tools/func.py", line 28, in __get__
value = self.fget(obj)
File "/home/odoo/src/odoo/16.0/odoo/tools/query.py", line 210, in _result
self._cr.execute(query_str, params)
File "/home/odoo/src/odoo/16.0/odoo/sql_db.py", line 321, in execute
res = self._obj.execute(query, params)
psycopg2.errors.SyntaxError: memory exhausted at or near ""login""
LINE 1: ...((("res_users"."login" = 'admin') OR ("res_users"."login" = ...
```
in 17.0 without this patch
```
>>> u.search(make_dom(1480))
res.users(2,)
>>> u.search(make_dom(1481))

```
This issue was observed in upgrades in multiple instances. Example: MRP
produces an OR domain with 2K terms for warehouse sub-locations that
fail.
