DbcpException: Backend Start-up Failed

We are trying to install DSPACE with POSTGRES. When we run the ant
fresh_install command we get a DbcpException. What could be causing an
org.apache.commons.dbcp.DbcpException: Backend start-up failed: FATAL:
Database "usr" does not exist in the system catalog.

I can run the command psql -d dspace -c "SELECT version();" on the postgres database and it returns the following:

version
--------------------------------------------------------------------------
PostgreSQL 7.3.4 on sparc-sun-solaris2.9, compiled by GCC gcc (GCC)
3.3.2
(1 row)

The error we are getting with the dspace install is as follows:
