If you take a peek at the man pages you'll see some thing like:

"The -n and -N switches have no effect when -t is used, because tables selected by -t will be dumped regardless of those switches, and non-table objects will not be dumped."

Try something like:

pg_dump -U postgres -t 1.activity -d geopostgrest -f activity_05-08-2015.sql
