PostgreSQL JDBC Driver for corresponding JDK/JVM.

Hi,

I'm checking PostgreSQL JDBC Driver.
I've downloaded RPM for PostgreSQL JDBC Driver from Yum Repository.
http://yum.postgresql.org/8.3/redhat/rhel-5-x86_64/repoview/postgresql-jdbc.html

And I checked the contents.
It seems some drivers(for jdbc2, jdbc2ee, jdbc3), but
it is just same symbolic link to postgresql-jdbc-8.3.607.jar.

# ls -l postgresql*
postgresql-jdbc-8.3.607.jar
postgresql-jdbc.jar -> postgresql-jdbc-8.3.607.jar
postgresql-jdbc2.jar -> postgresql-jdbc.jar
postgresql-jdbc2ee.jar -> postgresql-jdbc.jar
postgresql-jdbc3.jar -> postgresql-jdbc.jar

I think I should change jar file corresponding JDK/JVM version.
http://jdbc.postgresql.org/download.html#others


Also, newer version(9.1-901) has one jar but I don't know
which version of JDK/JVM is corresponding.

# ls -l postgres*
postgresql91-jdbc-9.1.901.jar
postgresql91-jdbc.jar -> postgresql91-jdbc-9.1.901.jar


Which JDK/JVM version is corresponding ?
