I am not sure I follow. Are you saying you eventually restore the data for that
table as a separate step? If so, from the previous link, this might help:
"
--disable-triggers
This option is only relevant when performing a data-only restore. It
instructs pg_restore to execute commands to temporarily disable triggers on the
target tables while the data is reloaded. Use this if you have referential
integrity checks or other triggers on the tables that you do not want to invoke
during data reload.
Presently, the commands emitted for --disable-triggers must be done as
superuser. So, you should also specify a superuser name with -S, or preferably
run pg_restore as a PostgreSQL superuser.
