Kako se ispravlja

Metod ispravke: Smernica ili zakrpa infrastrukture

If any regular or application users have been granted excessive administrative rights, those privileges should be removed immediately via the Yugabyte ALTER ROLE YSQL command. Using the same example above, the following YSQL statements revoke all unnecessary elevated administrative privileges from the regular user appuser: # whoami yugabyte # ysqlsh -c "ALTER ROLE appuser NOSUPERUSER;" ALTER ROLE # ysqlsh -c "ALTER ROLE appuser NOCREATEROLE;" ...
