 - If you have granted privileges to any users or roles for the affected pg_catalog tables and views, you encounter an error during the migration process. This error will be identified by the following pattern: **"pg_restore error: could not execute query GRANT/REVOKE PRIVILEGES on TABLENAME to username."**
 To resolve this error, it's necessary to revoke the select privileges granted to various users and roles on the pg_catalog tables and views. You can accomplish this by taking the following steps.
    1. Take a pg_dump of the database containing only the schema by executing the following command from a machine with access to your single server.
-    ```bash
+    ```sql
         pg_dump -h <singleserverhostname> -U <username@singleserverhostname> -d <databasename> -s > dump_output.sql  
     ```
    2.  Search for **GRANT** statements associated with the impacted tables and views in the dump file. These GRANT statements follow this format.
-    ```bash
+    ```sql
         GRANT <privileges> to pg_catalog.<impacted tablename/viewname> to <username>; 
     ```
    3. If any such statements exist, ensure to execute the following command on your single server for each GRANT statement. 
-    ```bash
-        REVOKE <privileges> to pg_catalog.<impacted tablename/viewname> from <username>; 
+    ```sql
+        REVOKE <privileges> ON pg_catalog.<impacted tablename/viewname> from <username>; 
     ```
