In PLPGSQL, does anyone know how to subtract MILLISECONDS from a field
defined as timestamp(3), yielding another field defined as timestamp(3)?
Have been trying interval, and conversion functions but no luck.
Example: '2006-10-17 14:23:28.951'; subtract 5 milliseconds from a field
called mytable.end_time, and return the results to a field named
work_timestamp.
work_timestamp := ????
