I assume that this behaviour makes change owner on a table change owner of serial sequences? Should we perhaps also propagate grant insert on a table to grant select, update on dependent serial sequences? Chris

Yeah. > Should we perhaps also propagate grant insert on a table to grant > select, update on dependent serial sequences? Doesn't really follow. That code is maintaining an invariant: the owner of a table owns the associated indexes, toast table, sequences, etc. There's no system-wide assumption that sequence privileges track table privileges. regards, tom lane

I brought this up a few months ago. Tom, weren't your objections based more on implementation concerns than on whether the idea itself had merit? http://archives.postgresql.org/pgsql-general/2004-10/msg00511.php -- Michael Fuhr http://www.fuhr.org/~mfuhr/

No, my point was that making implicit sequences work transparently requires more thought than this. I'd like to see a fairly complete plan put forward before we start installing random hacks on permissions. regards, tom lane
