I'm probably missing something stupid, but why does this happen?
ALTER TABLE list_parted2 ATTACH PARTITION part_7 FOR VALUES IN (7);
-INFO: partition constraint for table "list_parted2_def" is implied
by existing constraintsERROR: partition constraint is violated by some row
Based on the regression test changes made up higher in the file, I'd
expect that line to be replaced by two lines, one for
list_parted2_def_p1 and another for list_parted2_def_p2, because at
this point, list_parted2_def is a partitioned table with those two
children, and they seem to have appropriate constraints.
list_parted2_def_p1 hasCheck constraints: "check_a" CHECK (a = ANY (ARRAY[21, 22]))
list_parted2_def_p2 hasCheck constraints: "check_a" CHECK (a = ANY (ARRAY[31, 32]))
Well, if a is 21 or 22 for the first, or 31 or 32 for the second, then
it's not 7. Or so I would think.
