feat(db-postgres): deep querying on json and rich text fields

[r1tsuu]

What?

Allows to query on JSON / Rich Text fields in Postgres the same way as in Mongodb with any nesting level.

Example:
Data:

{
  json: {
    array: [
      {
        text: 'some-text', // nested to array + object
        object: {
          text: 'deep-text', // nested to array + 2x object
          array: [10], // number is nested to array + 2x object + array
        },
      },
    ],
  }
}

Query:

payload.find({
  collection: 'json-fields',
  where: {
    and: [
      {
        'json.array.text': {
          equals: 'some-text',
        },
      },
      {
        'json.array.object.text': {
          equals: 'deep-text',
        },
      },
      {
        'json.array.object.array': {
          in: [10, 20],
        },
      },
      {
        'json.array.object.array': {
          exists: true,
        },
      },
      {
        'json.array.object.notexists': {
          exists: false,
        },
      },
    ],
  },
})

How?

Utilizes the jsonb_path_exists postgres function

Approved. Looks like one merge conflict to resolve before it can be merged.
