OK, here is what I see:
from top:
17718 postgres 25 0 293M 293M 292M R 22.2 7.6 28:26 2
postgres: postgres mydb 127.0.0.1:41972 INSERT
MY OS command is:
pg_restore -v -t mytable -d mydb -U postgres -R my.dmp
SQL from database:
mydb=# select datname, procpid, current_query
mydb-# from pg_stat_activity
mydb-# where current_query != '<IDLE>';
datname | procpid |
current_query
---------+---------+----------------------------------------------------
------------------------------------------------------------------------
------------------------------------------------------------------------
-------------------------------------------------------------
mydb | 17718 | INSERT INTO mytable VALUES (...
(1 row)
Thanks,

Not for me...
That decision is fixed at pg_dump time; it's not possible for pg_restore
to change it, because the data is already that way (or not) in the dump
file. Maybe you misinterpreted what you saw?
