DESCRIPTION: Fixes potential memory corruptions that could happen when a Citus downgrade is followed by a Citus upgrade. In case of citus downgrade and further upgrade citus crash with core dump. The reason is that citus hardcoded number of columns in pg_dist_partition table, but in case of downgrade and following update table can have more columns, and some of then can be marked as dropped. Patch suggest decision for this problem with using tupleDescriptor->nattrs(postgres internal approach). Fixes #7933. --------- Co-authored-by: Onur Tirtir <onurcantirtir@gmail.com> |
