title: Cannot see body of function in Dbeaver/PgAdmin
body: <p>I connected to postgreSQL database (version 8.3) with DBeaver. When find function and try to see the body of it I got error message that there is <code>ERROR WHILE READING SOURCE: SQL Error [42883]: function pg_get_functiondef(oid) does not exists</code>.
  How can I overcome this?</p>
