出现了这个错误：ERROR: syntax error at or near "ROLE"

This error message usually indicates that there is a problem with the syntax of the SQL statement you are attempting to execute.

If you are trying to grant the CREATE ROLE privilege to a user or role, the correct syntax for the GRANT command is:

GRANT CREATE ROLE TO <username>;

Make sure that you have typed this command correctly, including the semicolon at the end. Also, check that you have specified the correct username for the user or role that needs the CREATE ROLE privilege.

If you are still encountering the syntax error, please provide more information about the SQL statement you are trying to execute, including the full text of the statement and any other relevant details.
