When client secrets are not base64 encoded, print an error message
that's not a generic base64 decode error:
client secrets must be base64 decodable. See issue #337.
Please consider replaceing "secret" with "c2VjcmV0"
When a user file is missing a mandatory field print an error message.
Unable to build Server: user elroy-foo is missing email field
For #400
The "redirectURLs" field in the client metadata has been updated
to the correct "redirect_uris". To allow backwards compatibility
use Postgres' JSON features to update the actual JSON in the text
field.
json_build_object was introduced in Postgres 9.4. So update the
documentations to require at least this version.
