To get at an editable script you can do something like:

pg_restore -f my_database_txt.sql  my_database.dump

This will give you a plain text version of the dump that you can feed 
back to psql to load into remote database.

If you want to do this in steps you can do:

pg_restore -s-f my_database_sch_txt.sql  my_database.dump

to get the object(schema) definitions only and then

pg_restore -a -f my_database_data_txt.sql  my_database.dump

to get the data definitions.
