There is a known bug with applying the same plpython trigger function to
multiple tables that have different rowtypes --- the rowtype info gets
cached for the first table the function is used with in a session, and
then inappropriately reused with the other tables.  Does this seem to
describe your observations?

Someone had promised to supply a fix, but I haven't seen it yet.
In the meantime the only known workaround is to create multiple
copies of the plpython function, one for each trigger.
