Clarification on description for :validate_uniqueness

[Nick-t-go]

In the docs under options section, it states for :validate_uniqueness:

Whether or not to run uniqueness validations, has potential pitfalls, use with caution (requires >= v0.27.0).

I'm assuming it means active record uniqueness validations. Is that what it means? If so can the text be changed to (I can open a PR if accepting community submissions):

Whether or not to run ActiveRecord uniqueness validations, has potential pitfalls, use with caution (requires >= v0.27.0).

This way it is consistent with the :validate description which explicitly states:

Whether or not to run ActiveRecord validations (uniqueness skipped). This option will always be true when using import!.

If this doesn't refer to active record uniqueness validations then this is not an issue and explicitly omitting ActiveRecord was intentional and I am just implying otherwise on my own.

Yes :validate_uniqueness is for ActiveRecord validations.

Possible to also add clarification for what the pitfalls are? They don't appear to be mentioned in the rest of readme.

Using :validate_uniqueness will require a sql query per record...so it is basically N+1 queries.
