%description
     PostgreSQL is a sophisticated Object-Relational DBMS, supporting
     almost all SQL constructs, including subselects, transactions,
     and user-defined types and functions. It is the most advanced
     open-source database available anywhere.

     Options:
     --define 'with_openssl %{with_openssl}'
     --define 'with_odbc %{with_odbc}'
     --define 'with_perl %{with_perl}'
     --define 'with_tcl %{with_tcl}'
