Symptoms

When you try to install Bamboo and configure it to use PostgreSQL 9.1, it says that "Driver class cannot be found in the classpath"

Cause

Although our documentation says that Postgresql 8.2+ is supported, it also says that the PostgreSQL driver version is 8.4.x. However, the driver version 8.4.x don't support PostgreSQL 9.1.

This is being tracked in this Improvement Request:  BAM-11913 - Getting issue details... STATUS

Resolution

The workaround is to replace the existing driver located at <Bamboo_Install>\webapp\WEB-INF\lib\postgresql-8.4-701.jdbc3.jar by the driver that supports PostgreSQL 9.1, and restart the Bamboo server.
