    Metadata details:
    filename: 20210821082834_change_password_payload_to_text.rb
    path of file: ./repos/PasswordPusher/db/migrate
    
    the code of the file until where you have to start completion: # frozen_stri
    
  def change
    # https://sqlines.com/postgresql/datatypes/text
    # CHAR(n)	    Fixed-length	  1 ⇐ n < 1 Gb	Default is 1
    # VARCHAR(n)	Variable-length	1 ⇐ n < 1 Gb	Default is 1 Gb

    # Both TEXT and VARCHAR have the upper limit at 1 Gb, and there is no performance
    # difference among them (according to the PostgreSQL documentation).
    change_column :passwords, :payload, :text
  end
