Endlessly extending the COPY command doesn't seem like a winning
proposition to me and I think if we aren't comfortable telling every user
to write a script to pre/post-process the data we should instead provide a
bulk loader/unloader that transforms things to our limited COPY
functionality. There are all kinds of feature requests I've seen
along these lines that would make COPY a million option mess if we try to
support all of it directly.
- skipping header rows
- skipping certain data file columns
- specifying date formats
- ignoring duplicates
- outputting an arbitrary SELECT statement

TIP 2: you can get off all lists at once with the unregister command
(send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
