Hello Alvaro, Please look at an anomaly introduced with b0e96f311. The following script: CREATE TABLE a (); CREATE TABLE b (i int) INHERITS (a); CREATE TABLE c () INHERITS (a, b);
ALTER TABLE a ADD COLUMN i int NOT NULL; results in: NOTICE: merging definition of column "i" for child "b" NOTICE: merging definition of column "i" for child "c" ERROR: tuple already updated by self (This is similar to bug #18297, but ATExecAddColumn() isn't guilty in this case.) Best regards, Alexander
