Michael Andre Pearce (IG) commented on HAWQ-393:
------------------------------------------------
I mean server should show hcatalog in database list, and be able to list
schema, tables and describe tables just like any others, with if needed
commands translated.
If you go the route of client side implementation, you then need to take care
of this in all the clients including odbc and rather than piggy back postgres
ones you will end up with having to write/maintain these yourselves to me that
sounds more of a headache personally.
Either way of implementing (client or server side) taking just the view of an
end user rather than a developer, i would expect odbc compliance, for such
tools like tableau, excel, powerbi to work with.

> Key: HAWQ-393
> URL: https://issues.apache.org/jira/browse/HAWQ-393
> Project: Apache HAWQ
> Issue Type: New Feature
> Components: Hcatalog, PXF
> Reporter: Goden Yao
> Assignee: Oleksandr Diachenko
> Fix For: 2.0.0
>
>
> As a Hawq user, after enabling hcatalog integration feature,
> I want to be able to display (\d) tables in hcatalog so that I know what
> tables are available and the contents of their schemas.
> *Acceptance Criteria*
> 1. Ability to describe a single table.
> {code}
> \d hcatalog.databaseName.t1
> {code},
> {code}
> \d+ hcatalog.databaseName.t1
> {code}
> 2. Ability to describe the every table in a database of hcatalog:
> {code}
> \d hcatalog.databaseName.*
> {code}
> 3. Ability to list tables that match patterns (only wildcard is supported)
> e.g.
> {code}
> \d hcatalog.databaseName.prefix_*
> {code}
> 4. Ability to list databases in hcatalog:
> {code}
> \d hcatalog.*
> {code}
> 5. Tab autocomplete of items from hcatalog. (optional)
> [1] based on current implementation, we cache the meta data from hcatalog
> within the same transaction.
