Parallel pg_restore unsupported
I don't know why, but I have as server Postgres 9.3 and psql, pg_restore and pg_dump belong to version 9.2.

/usr/bin/pg_restore is version 9.2, but /usr/pgsql-9.3/bin/pg_dump is version 9.3.

This is the cause of the problem.

The solution is simply:

yum remove postgresql
