>
> 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. Ability to list databases in hcatalog:
> {code}
> \l hcatalog
> {code}
> 5. Tab autocomplete of items from hcatalog.
> [1] based on current implementation, we cache the meta data from hcatalog
> within the same transaction.
