title: Union (or) type in sql
body: <p>I want a column in my table to be able to take one of two data types. Specifically I want it to take either a dictionary or a string. </p>
  
  <p>If the column is called column1 then I would like the type in the table would look something like </p>
  
  <p>column1 JSONB or TEXT</p>
  
  <p>Is this possible in SQL? Also, I know it is oftentimes considered bad practice to put dictionaries in tables.</p>
