CE looked like it was just for parent/child relationships ... did I read
that right? I'm not sure how it applies. And the table partitioning
looks like its still on the todo list ... is that really the case?
And as for getting data into the DB ... from earlier posts it sounded
like standard practice was to bulk load the new data into a temporary
table and then do an INSERT ... SELECT to load the data into the new
table. Is this still the case with the trigger, or can/should I just
COPY the data straight into the final database? And I assume that I
should *not* delete my indexes while I'm loading the table, since the
queries in the trigger can take advantage of them ... right?
Also, as a slight aside, has anyone created a data type for single IPs
that is essentially an integer (i.e. 4 bytes) that works with the
standard functions for INET?
