[ckan-dev] Dataset upload error

[Cliff Ingham]

I finally found the _table_metadata table.  It's in the datastore
database.  According to the documentation, this should be owned by the
writeuser, which it was.

I had to grant select permission on that table to the readonly user.  I
don't think the datastore setup script set this correctly.

Other than the possible problem with the datastore database setup
script, I think this is just documentation confusion - especially given
that I am new to Python applications and Postgresql.

Which db user and which database?

This is a source install, cloned from the master branch.  (Yes, I know
there could be problems)  However, this was not something that was
expected to be broken.  I just recently upgraded to the latest commit,
as of sometime on Tuesday.

No, nothing custom:
ckan.plugins = stats text_preview recline_preview datastore datapusher
spatial_metadata spatial_query
