A superuser is considered to 'own' all objects and so 'ALL' and 'OWNED'
above would be the same when issued by a superuser, in the current
implementation.
Looking at DROP OWNED and REASSIGN OWNED, they operate at the more
specific level of "OWNED" == "relowner" rather than if the role is
considered an 'owner' of the object through role membership, as you are
implying above.
As such, I'll rework this to be more in-line with the existing OWNED BY
semantics of REASSIGN OWNED BY and DROP OWNED BY, which means we'd have:
ALTER TABLESPACE name MOVE [ ALL | OWNED [ BY reluser ] ]
[ TABLES | INDEXES | MATERIALIZED VIEWS ] TO name opt_nowait
eg:
ALTER TABLESPACE tblspc1 MOVE ALL TO tblspc2;
ALTER TABLESPACE tblspc1 MOVE OWNED TO tblspc2;
ALTER TABLESPACE tblspc1 MOVE OWNED BY myrole TO tblspc2;
ALTER TABLESPACE tblspc1 MOVE TABLES OWNED BY myrole TO tblspc2;
ALTER TABLESPACE tblspc1 MOVE ALL OWNED BY myrole TO tblspc2;
Thoughts?
Thanks,
Stephen
