FWIW, I tried to reproduce this using the attached example. Works
fine here. However, this report sounds quite a lot like some partitioning
bugs that have been fixed in the past. Could you update to 11.4 and try
again? If it still fails, then there's some aspect of your problem table
that you have not told us about.

drop table if exists pparent;

create table pparent(f1 int, z int, f2 int, my_timestamp timestamptz, f3 int)
partition by range (my_timestamp);

alter table pparent drop column z;

create table defchild (f1 int, f2 int,
bogus1 text, my_timestamp timestamptz, bogus2 text, f3 int);

alter table defchild drop column bogus1, drop column bogus2;

alter table pparent attach partition defchild default;

create table otherchild (like defchild including all);

alter table pparent attach partition otherchild
for values from ('2019-01-01') to ('2020-01-01');
