MDEV-28576 RENAME COLUMN with NOCOPY algorithm leads to corrupt partitioned table
10.5 part: test cases and comments.
The code is in the merge commit 74fe1c44aa1
When f.ex. table is partitioned by HASH(a) and we rename column `a' to
`b' partitioning filter stays unchanged: HASH(a). That's the wrong
behavior.
The patch updates partitioning filter in accordance to the new columns
names. That includes partition/subpartition expression and
partition/subpartition field list.
