OK - I've found the problem - two records had [valid but] peculiar dates -
we were trying to backfill the database from manual records.
You can replicate the problem by creating a record from random [valid] data,
then running the update query:
update staff set dob = '0001-01-01 BC' where sid = <your record number>
This will reproducibly produce the error noted when the table is queried
(brief experimentation suggests that any BC date will do).
It's no longer a problem for me (I've simply set the dob in the records
concerned to NULL - I don't have many staff over 2000 years old!!) but I
guess you might want to see if the error is Microsofts or in PGAdmin
(someone might have more need to store BC dates than I do).
As stated before - I am working with PGAdmin 1.2.0.
