"alter table rename" does not update constraints - Mailing list pgsql-general

Hi there,

I successfully renamed one of the columns of the primary key of one of
my tables (it is used in one of the foreign keys, too -- I think, this
is the problem). Unfortunately, the constraint (rule system?) wasn't
updated by "alter table" -- have a look:

----------------------------------------------------------------------
  db=# create table blatt_schaeden (
               nummer smallint not null,
               datum date not null,
               typ smallint not null,
               klasse smallint,
               schaden smallint,
               primary key (nummer,datum,typ),
               foreign key (nummer) references blatt,
               foreign key (typ) references blatt_schadenstyp
               );
  CREATE
  db=# alter table blatt_schaeden rename column nummer to blatt_nummer;
  ALTER
  db=# update blatt_schaeden set klasse = 0 where schaden=0;
  ERROR:  constraint <unnamed>: table blatt_schaeden does not have an attribute nummer
----------------------------------------------------------------------

Do you consider this as a bug? There are similar items in the TODO
file, related to "alter table add" ...

Thanks for your attention,
