Oh! Yes, that's to be expected, because so far as Postgres is concerned
it's logging the location of the RAISE WARNING command. You've only
told it to print the SQLERRM string, and nothing else:
RAISE WARNING 'An error occurred while trying to rotate the live user
activity records; code %: %', SQLSTATE, SQLERRM;
As of 9.2 there is a way to get the context string for the original
error (GET STACKED DIAGNOSTICS) which you could then include in the
RAISE message. That hasn't made it to any released versions
unfortunately.
