[ckan-dev] datastore upsert api

Mon Oct 12 10:06:17 UTC 2015

Just to revive this a little, I've noticed two things:
- Setting a primary key doesn't require restating the columns
- Restating the columns (with or without adding a new column) does not
allow you to try and change their types. No error for integer->float, just
ignored.
