Bug #434: Maximun number of connections

Sergio Muscat (sergio(at)onvol(dot)net) reports a bug with a severity of 2
The lower the number the more severe it is.

Short Description
Maximun number of connections

Long Description
What is the maximum number of connections that postgresql can support? I am writing a connection pool using jdbc/tomcat and when the number of connections exceeds about 30 items, an exception is raised saying 'sorry too many clients already'. Is this normal? See below for a dump of the exception.

Regards,

Sergio
