Thread: pgsql: Fix the problem of GRANTs creating "dangling" privileges not

Log Message:
-----------
Fix the problem of GRANTs creating "dangling" privileges not directly
traceable to grant options.  As per my earlier proposal, a GRANT made by
a role member has to be recorded as being granted by the role that actually
holds the grant option, and not the member.
