If you don't have any dependencies on the information schema (that is, 
you have yourself created objects that refer to the information schema, 
which should be rare), it is safe to just drop the schema, that is,

DROP SCHEMA information_schema CASCADE;

and reload it

psql -f .../information_schema.sql $PGDATABASE
