> 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 whole schema:
> {code}
> \d hcatalog.databaseName.*
> {code}
> 3. Ability to list tables that match wildcards
> e.g.
> {code}
> \d hcatalog.databaseName.prefix_*
> {code}
> 4. Tab autocomplete of items from hcatalog which HAWQ has queried within the same transaction. [Stretch goal]
> [1] based on current implementation, we cache the meta data from hcatalog within the same transaction.
