  1. sql: disallow using cluster_logical_timestamp as column default when … 

    …backfilling

Previously, `ADD COLUMN ... DEFAULT cluster_logical_timestamp()` would
crash the node and leave the table in a corrupt state. The root cause
is a nil pointer dereference. This commit fixed it by returning an
unimplemented error and hence disallow using this builtin function as
default value when backfilling.

Release note (bug fix): fixed a bug as detailed in cockroachdb#98269.
