If you are still getting an AbstractMethodError for
org/postgresql/jdbc1/Statement.getConnection, it most likely means
pg72jdbc1.jar is lurking somewhere on your classpath.  The easiest
thing to do is simply remove the file entirely from your filesystem.
(It is only necessary if you're writing JDBC applications for
PostgreSQL in Java 1.1, which I don't think you are.)

To find the offending file, you can do something like this:

|$ slocate -r 'jdbc.*\.jar'
|/usr/share/tomcat/common/lib/jdbc2_0-stdext.jar
|/opt/resin/2.1.4/lib/jdbc2_0-stdext.jar
|/opt/resin/2.1.4/lib/jdbc-mysql.jar

(Your output will be different.)

Once you found it, you can do

$ cd /your/path/to/offending/file/
$ mv pg72jdbc1.jar pg72jdbc1.jar.removed

We ship the correct PostgreSQL JDBC driver as part of our
distribution.  The file is called postgresql.jar:

|$ slocate postgresql.jar
|/var/vadim/p4checkout/core-platform/dev/lib/postgresql.jar
|/var/vadim/p4checkout/core-platform/5.2/lib/postgresql.jar
|/var/vadim/p4checkout/core-platform/6.0/lib/postgresql.jar
|/var/ccm-devel/web/vadim/dev/webapps/WEB-INF/lib/postgresql.jar
