Thread: pgsql: amcheck: Add additional TOAST pointer checks.

amcheck: Add additional TOAST pointer checks.

Expand the checks of toasted attributes to complain if the rawsize is
overlarge.  For compressed attributes, also complain if compression
appears to have expanded the attribute or if the compression method is
invalid.
