Sasha 98fec35368 fix(db-postgres): incorrect pagination results when querying hasMany relationships multiple times (#11096)
Fixes https://github.com/payloadcms/payload/issues/10810

This was caused by using `COUNT(*)` aggregation instead of
`COUNT(DISTINCT table.id)`. However, we want to use `COUNT(*)` because
`COUNT(DISTINCT table.id)` is slow on large tables. Now we fallback to
`COUNT(DISTINCT table.id)` only when `COUNT(*)` cannot work properly.

Example of a query that leads to incorrect `totalDocs`:
```ts
const res = await payload.find({
  collection: 'directors',
  limit: 10,
  where: {
    or: [
      {
        movies: {
          equals: movie2.id,
        },
      },
      {
        movies: {
          equals: movie1.id,
        },
      },
      {
        movies: {
          equals: movie1.id,
        },
      },
    ],
  },
})
```
