Use psql instead with command
psql -U username databasename -f yourdb_file.sql
Yes you will have to edit the file a bit.
Drawbacks are :
triggers will go of on all insert and will be stumbling block in case to
dump you may use the following command in future
pg_dump --disable-triggers -U <user_name> -a -d -b -D -Fc -Z 9 -f
<filername.tar.gz> <dbname>
and to restore use
pg_restore --disable-triggers -U <user_name> -d <dbname>
<backupfilename.tar.gz>
