Demonstrate Postgres concurrent index error

[dashrews78]

I was researching how to create postgres indexes concurrently. The documents clearly state to add it to the options. This can be seen in the docs:
https://gorm.io/docs/indexes.html

Due to go-gorm/postgres#288 this no longer works.

When I went to do this I received an error. Such as

CREATE INDEX CONCURRENTLY IF NOT EXISTS "field_idx" ON "test_table" USING btree("idx") CONCURRENTLY

So I reproduced it here by stripping down the playground to only run Postgres. I added an index to one of the fields in the model. As you can see from the results the same error was received.
