I see: the function you originally posted is called by a trigger
function.  In any case the answer is the same: functions can't start
or end transactions because they're already being executed in the
context of an outer transaction.  My previous message mentioned
using dblink as a way around that, but that's not necessarily good
design -- one problem is that if the outer transaction rolls back
then transactions that have already been committed over a dblink
connection won't be rolled back.  Doing transaction control from
outside the functions would probably be better.
