Similar to: #42378
Tried adding test cases for the changes but
migration file would always use id as primary_key_type
and reference type as foreign_key_type. Did not find
any good way to assert the changes.
Tested locally and following is the schema
generated for Action Text migration if
`primary_key_type: :uuid`
```
create_table "action_text_rich_texts", id: :uuid, default: -> { "gen_random_uuid()" }, force: :cascade do |t|
t.string "name", null: false
t.text "body"
t.string "record_type", null: false
t.uuid "record_id", null: false
t.datetime "created_at", precision: 6, null: false
t.datetime "updated_at", precision: 6, null: false
t.index ["record_type", "record_id", "name"], name: "index_action_text_rich_texts_uniqueness", unique: true
end
```
In MySQL, the text column size is 65,535 bytes by default (1 GiB in
PostgreSQL). It is sometimes too short when people want to use a text
column, so they sometimes change the text size to mediumtext (16 MiB) or
longtext (4 GiB) by giving the `limit` option.
Unlike MySQL, PostgreSQL doesn't allow the `limit` option for a text
column (raises ERROR: type modifier is not allowed for type "text").
So `limit: 4294967295` (longtext) couldn't be used in Action Text.
I've allowed changing text and blob size without giving the `limit`
option, it prevents that migration failure on PostgreSQL.
