title: ERROR: row is too big: size 8168, maximum size 8164
body: <p>I'm using PostgreSql 9.2
  And i have a lot of roles, and all of them have been granted USAGE privileges on a schema.
  And when i try to create new user and grant privilege i receive an error: </p>
  
  <p><code>CREATE ROLE my_user;
   GRANT USAGE on schema my_schema to my_user;
   ERROR: row is too big: size 8168, maximum size 8164</code></p>
  
  <p>I have read a lot about how to fix it, but it was an really old articles. 
  Is there any new version of PostgreSql (9.6.8 +) where this bug is fixed?</p>
