Bug reference:      2787
Logged by:          Pete Deffendol

PostgreSQL version: 8.1.5
Operating system:   Red Hat Enterprise 4
Description:        postgresql-jdbc-8.1.407 won't install on RHEL4
Details: 

When attempting to install
ftp://ftp8.us.postgresql.org/postgresql/binary/v8.1.5/linux/rpms/redhat/rhel
-es-4/postgresql-jdbc-8.1.407-4PGDG.i686.rpm the installer reports the
following:

error: Failed dependencies:
        /usr/bin/rebuild-gcj-db is needed by
postgresql-jdbc-8.1.407-4PGDG.i686

It appears that some other distributions (Fedora?) package this file up with
java-1.4.2-gcj-compat.  However, the Red Hat version
java-1.4.2-gcj-compat-1.4.2.0-27jpp doesn't do it.
