Try "man createlang" - you need to turn a language on for each database that
needs it.
The docs for plpgsql have been much updated in the 7.1 docs and there are
some useful examples in Roberto Mello's cookbook at
techdocs.postgresql.org - there is a host of other stuff there too including
some examples of trigger usage in my "postgresql notes".
