The ROLE_ROUTINE_GRANTS table
      provides information about the routine privileges for roles that
      are available to or granted by the currently enabled roles.
    
      The ROLE_ROUTINE_GRANTS table has
      these columns:
- GRANTOR- The user name part of the account that granted the role. 
- GRANTOR_HOST- The host name part of the account that granted the role. 
- GRANTEE- The user name part of the account to which the role is granted. 
- GRANTEE_HOST- The host name part of the account to which the role is granted. 
- SPECIFIC_CATALOG- The name of the catalog to which the routine belongs. This value is always - def.
- SPECIFIC_SCHEMA- The name of the schema (database) to which the routine belongs. 
- SPECIFIC_NAME- The name of the routine. 
- ROUTINE_CATALOG- The name of the catalog to which the routine belongs. This value is always - def.
- ROUTINE_SCHEMA- The name of the schema (database) to which the routine belongs. 
- ROUTINE_NAME- The name of the routine. 
- PRIVILEGE_TYPE- The privilege granted. The value can be any privilege that can be granted at the routine level; see Section 15.7.1.6, “GRANT Statement”. Each row lists a single privilege, so there is one row per column privilege held by the grantee.
