Hi David, and thanks for getting back to me.

Ah, yes, it now makes perfect sense...
All statements in a transaction which is READ COMMITTED sees the data
as of CLOCK_TIMESTAMP() and all statements in a transaction that is
SERIALIZABLE see the data as of TRANSACTION_TIMESTAMP().
At least, that's how I understand it now - my error was not
double-checking my function definitions.
Thanks again and rgs,
Pól Ua Laoínecháin...
