Just to follow up on this with a look at check digit generation and checkin:
Luhn's algorithm should do for the check digit, I think. It need not be
anything complex given the chances for collision in the sample space.
Additionally, it's commonly used, easily implemented and widely
understood

Anyone know how to install Postgresql as a windows service from the command
line.
I have this as the correct syntax:

I have a problem with a query wich simple aggregate values. In the sample

Date and time functions like current_time return the client machine's
time. Is there a way of getting the database server's time? I have a
situation that requires comparison of a date stamp on records with
today, but I need to avoid the possibility of a user changing their
computer's clock

Er, no they don't. They return the server's time, adjusted to the
client's time zone if the client specified its time zone using SET TIMEZONE.
At least, that's how they behave here, and I can't
