Ah, the trick is to use the Anum_xxx, of course. I couldn't get rid of thinking how to dynamically access by name... will have a try at that, thanks for the idea. > You could do a generic heap_open() on the catalog using the OID, > and then use heap_modify_tuple to apply the namespace column update. Thanks for pointing me to the right APIs: finding them is where the time is mostly spent as far as I'm concerned. > It might be nice to include the "object already exists" check here > too, which could probably be done if in addition the column number > of the name column were passed in. Permission checks too, if the > owner column number were passed in. Etc. Well it seems that depending on the object, sometime only superusers are allowed to edit things, and sometime the owner too. Will add a boolean superuser_only in the prototype.
