Yes, and I can do this outside pkg_chk like the following

   #!/bin/sh

   set -e

   pkg_update_summary -r \
      /usr/pkgsrc/packages/All/pkg_summary.gz /usr/pkgsrc/packages/All \
      'gzip -dc' 'gzip'

   pkg_chk "$@"

That is pkg_summary.txt is always updated if it is necessary.

If some packages were deleted, pkg_update_summary updates summary
correctly. Copying preserving timestamps? I don't do this :)
Can you explain how this may happen?
