>                 Key: SIS-358
>                 URL: https://issues.apache.org/jira/browse/SIS-358
>             Project: Spatial Information Systems
>          Issue Type: Improvement
>          Components: Metadata
>    Affects Versions: 0.8
>         Environment: PostgreSQL 9.6.
>            Reporter: Martin Desruisseaux

> The {{org.apache.sis.metadata.sql}} package takes advantage of table inheritance as documented
there:
>     http://www.postgresql.org/docs/9.6/static/ddl-inherit.html
> However as of version 9.6, PostgreSQL does not support index inheritance. This limitation
is documented in the "Caveats" section at the bottom of the above-cited page. The consequence
is that {{org.apache.sis.metadata.sql}} can not enforce foreigner key constraints on columns
that reference a parent table.
> If PostgreSQL supports index inheritance in a future version, then the {{Dialect.isIndexInheritanceSupported}}
constant should be set to {{true}}.
