Hi Brent,
Yes I think it's possible, simply playing with the TARGET COLUMNS clause of the pgloader command. Would you mind
openingan issue on Github, where I track bug fixes and user requests, so that our conversation is then publicly
archivedand available to other PostGIS and pgloader users?
Thanks,
