JDBWC v1.0.0-4 SQL Client compatibility

PostgreSQL metadata support has been added for SQL Client compatibility. A further update for the PostgreSQL metadata is expected before the files are made available in the official releases (downloads).

The updated Install doc (TODO section) explains the next main steps for the drivers evolution. In summary the next release will see database specific functionality migrated into brand-name packages so more databases can be supported by the driver.
The release following that will be oriented towards query synchronization which should also provide some of the ground work for using thread stacks.
