Bug reference: 6640
Logged by: Regina Obe

PostgreSQL version: 9.1.3
Operating system: Any
Description:
This seems to be only an issue if a user individually chooses to backup a
table marked as editable in an extension, but works fine if full backup is
chosen.
The particular extension in question here is PostGIS.
Please refer to:
http://trac.osgeo.org/postgis/ticket/1815
for details.
In short -- if I do a full backup of a database, a table marked as editable
gets its data backed up as expected, but if I try to backup a schema the
table is in or the table itself, pg_dump does not dump anything.
