schema default privilege owner not showing

Hi,

Trying out assigning privileges such as:

ALTER DEFAULT PRIVILEGES IN SCHEMA schemaname GRANT SELECT ON TABLES TO grp_read;
ALTER DEFAULT PRIVILEGES FOR ROLE usr_1 IN SCHEMA schemaname GRANT SELECT ON TABLES TO grp_read;
ALTER DEFAULT PRIVILEGES FOR ROLE usr_2 IN SCHEMA schemaname GRANT SELECT ON TABLES TO grp_read;

When viewing the pgadmin "SQL" tab for the "schemaname" schema, all of these just show as:

ALTER DEFAULT PRIVILEGES IN SCHEMA schemaname GRANT SELECT ON TABLES TO grp_read;
ALTER DEFAULT PRIVILEGES IN SCHEMA schemaname GRANT SELECT ON TABLES TO grp_read;
ALTER DEFAULT PRIVILEGES IN SCHEMA schemaname GRANT SELECT ON TABLES TO grp_read;

As such, it's not possible to tell the difference and which role these are assigned to.

\ddp schemaname in psql seems to show "Owner" for Default access priveleges - I don't know whether this could be read into the SQL tab?

For reference - i'm setting by user but was also hoping to set just by a group (grp_read) role but that doesn't seem to be possible

Thanks in advance

Andy
