Pull request overview
This PR addresses a GCC 11/C++20 build failure in ColumnLowCardinality::SaveBody by avoiding a deprecated enum-to-enum bitwise operation during low-cardinality index serialization. It is a narrowly scoped compatibility fix in the native protocol serialization path for low-cardinality columns.
Changes:
- Cast the
IndexTyperesult touint64_tbefore combining it with the serialization flag bit. - Preserve the serialized wire-format value while avoiding the compiler warning that becomes an error under
-Werror.
