    Description

      We have received a request to add foreign keys to a table instantly but validating the existing data at a later stage.
      According to the customer, this feature is supported by PostgreSQL (NOT VALID keyword).
      https://dba.stackexchange.com/a/271585

      Currently adding a foreign key locks the table and it is not supported by ALTER TABLE ... ALGORITHM=INSTANT.
