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:
