how get "/var/db/pkg"?

[xiang]

Today,i run "pkgdb -F",but get a error message:"you do not own
/var/db/pkg",becouse i had delete /var/db/pkg by oversight just the other
day.
and i install som ports by "pkg_add" just now, then i can get
/var/db/pkg,but only a record of few ports in /var/db/pkg.
As a result,It do not show all ports that had installed in my machine when i
run "pkg_info" or "pkg_version".and i do not use "portupgrade" upgrade all
ports!
how can i do now?
