Problem in creating the database

When I run the following command:
psql -U postgres -d simdb -f setupSimDB.sql

With psql version 9.4.6 I encounter the following problem.

ALTER FUNCTION
psql:setupSimDB.sql:178: ERROR: syntax error at or near "."
LINE 11: ...ELECT pg_total_relation_size(\'' || user_name || '.scenarios...
                                                              ^
psql:setupSimDB.sql:180: ERROR: function administration.calculate_campaign_size(integer) does not exist
CREATE FUNCTION

psql:setupSimDB.sql:1864: ERROR: syntax error at or near "\"
LINE 95: type_string text DEFAULT \'\'
                                       ^

Any suggestions?
Thanks in advance.
