postgresql7.4 can't start (SSL)

Hello,

I installed postgresql 7.4 on Ubuntu Breezy with libpq.dev and an error
occurs at postgres start (/etc/init.d/postgresql7.4 start) :

* Starting PostgreSQL 7.4 database server: main The PostgreSQL server
failed to start. Please check the log output:
/usr/lib/postgresql/7.4/bin/postmaster: TCP/IP connexion must be
activated with SSL

Thanks if you can help me.
