This is caused by using a regclass
in columnar.options
instead of the storage ID.
As discussed with Jeff, the problem occurs because during the ALTER TABLE process, PG creates a new copy of the original table and the copy does not have the same table OID yet so it compresses with its default zstd format instead.
Compressed with `lz4'.
Now it's compressed with
zstd
.New stripes are compressed with
lz4
again.
