To give a user or group the right to install files and create functions in an Aster instance, a database administrator must use one of GRANT commands that gives the user privileges in the context of a schema:
GRANT { INSTALL FILE | CREATE FUNCTION } [, ...] [ PRIVILEGE ] ON SCHEMA schemaname [, ...] TO { username | GROUP rolename | PUBLIC } [, ...]
There is no support for delegating privilege management, because the WITH GRANT OPTION clause is not supported.
