Hm, I think that confirms my idea about the underlying nature of the bug.
The parent's stored expression for volume would refer to dimensions as
being var 13. Now, when you create a new child partition it would have no
dropped columns, so that dimensions would be column 11 and purchasingprice
would be column 13 in the child. Thus, the observed symptom is explained
if we failed to renumber the vars in the GENERATED expression while copying
it to the child partition.
However, AFAICT we do that correctly. I didn't bisect, but I think
this was fixed by commit d9253df12, which shipped in PG 12.5.
Please double-check your server version, eg with "select version();"
