If you want to modify or run in in a better time then you probably need 
to know it before running pkg install / pkg upgrade command. Then you 
probably need to fetch a package alone (pkg upgrade with -f or 
--fetch-only) and then you can unpack +MANIFEST from it and use some 
JSON / YAML tool to examine content (e.g. textproc/jq). After that you 
can run pkg upgrade (or pkg install) again with -I or --no-install-scripts.

You can get the list of the installed files by "pkg info -l pkgname" or 
"pkg query '%Fp' pkgname"
