Hi,
I want to default some columns for this COPY command only. So DEFAULT is not appropriate in this case. In fact I think you suggested a workaround right ? Doing an alter table before and another one after will work ... not fully clean thought since my user may not have the write to modify the table. Being able to specify default values directly in the COPY command will be really nice :-) I just wanted to share my tought :-)
Being eable to read zipped file will be cool to .. but I'm not sure it's Chrismas yet right so I didn't ask ;-)
Thanks for your help /David
David,
If you use a simple wrapper around copy using DBI (as either an untrusted perl database function) or straight perl, you could read zipped files as a filehandle.
As for defaults, you could also write a trigger to accomplish the "default" behavior or, if you use the above perl-based loader, you could implement defaults as well....

There's always ALTER TABLE ... SET DEFAULT.
