When we use the `|` (or) version of this rule the ORM generates two
sub-queries when checking the company. This causes sub-optimal and in
some cases really bad planning for the queries and thus PG takes hours
to complete them.
Example (formatted):
```sql
SELECT "mrp_routing_workcenter".id
FROM "mrp_routing_workcenter"
LEFT JOIN "mrp_bom" AS "mrp_routing_workcenter__bom_id"
ON "mrp_routing_workcenter"."bom_id" = "mrp_routing_workcenter__bom_id"."id"
WHERE "mrp_routing_workcenter"."workcenter_id" in (1)
AND ( ("mrp_routing_workcenter"."bom_id" in (
SELECT "mrp_bom".id
FROM "mrp_bom"
WHERE ("mrp_bom"."company_id" in (1))
)
)
OR ("mrp_routing_workcenter"."bom_id" in (
SELECT "mrp_bom".id
FROM "mrp_bom"
WHERE "mrp_bom"."company_id" IS NULL
)
)
)
ORDER BY "mrp_routing_workcenter__bom_id"."sequence",
"mrp_routing_workcenter__bom_id"."id",
"mrp_routing_workcenter"."sequence",
"mrp_routing_workcenter"."id"
```
If we use the single term version the generated query has only one
sub-query:
```sql
SELECT "mrp_routing_workcenter".id
FROM "mrp_routing_workcenter"
LEFT JOIN "mrp_bom" AS "mrp_routing_workcenter__bom_id"
ON "mrp_routing_workcenter"."bom_id" = "mrp_routing_workcenter__bom_id"."id"
WHERE "mrp_routing_workcenter"."workcenter_id" in (1)
AND ( ("mrp_routing_workcenter"."bom_id" in (
SELECT "mrp_bom".id
FROM "mrp_bom"
WHERE (("mrp_bom"."company_id" in (1))
OR ("mrp_bom"."company_id" IS NULL))
)
)
)
ORDER BY "mrp_routing_workcenter__bom_id"."sequence",
"mrp_routing_workcenter__bom_id"."id",
"mrp_routing_workcenter"."sequence",
"mrp_routing_workcenter"."id"
```
In this version PG is able to produce a better query plan resulting in
better execution times.
Also, the `company_id` field is required on some models, so the "= False" comparison is useless.
