"idle" is fine, "idle in transaction" is not so fine, because those
might be holding locks that block things like schema changes. You need
to figure out why your client-side code isn't closing out its
transactions promptly.
You'd probably be better off asking on the pgsql-jdbc list about this,
as the folks likely to know about Java-stack issues hang out there.
