Hi,
A while ago on a different SQL platform, I had the idea to use negative
numbers as id's for certain system records that I didn't prefer to have
interspersed with other records in a table. (For example, we had
"template" records which we used to spawn new records, and rather than
store them in a different table we just had records id=-1,-2 etc and
did an insert/select to create new "live" rows based on the templates).
Preventing them from displaying in the results was as simple as
ensuring that all select statements had a "id > 0" statement in them..
I'm wondering if there are any Bad Things that happen if I use negative
integers for primary key values in Postgres (v8.2)? My primary keys are
all bigserial type.
Any comments or advice?
Thanks!
Steve
