Re: Role Attribute Bitmask Catalog Representation

The fact that the ROLE_ATTR_* definitions are in pg_authid.h means that
there are now a lot of files that need to include that one.  I think the
includes relative to ACLs and roles is rather messy now, and this patch
makes it a bit worse.

I think we should create a new header file (maybe acltypes.h or
acldefs.h), which only contains the AclMode and RoleAttr typedefs and
their associated defines; that one would be included from parsenodes.h,
acl.h and pg_authid.h.  Everything else would be in acl.h.  So code that
currently checks permissions using only acl.h do not need any extra
includes.
