[ADMIN] Extension prevents dumping table?

[Chander Ganesan]

With PostGIS 2.0 if I load/install postgis using the command:

create extension postgis schema postgis;

And then use the command:

pg_dump -t postgis.spatial_ref_sys dbname > spatial_ref_sys.sql

I get an output that contains a few "set" statements, but no table
definition or data from the table.

However, if I install the PostGIS components the "old" way (not using
the extension loader), the pg_dump of the table works just fine.

Any ideas how to fix this or why this happens?

thanks

I don't think there is anything to "fix". If the table is part of the
extension then it should not get dumped separately. I don't know enough
about PostGIS to know if there's a valid reason to want to dump that
table by itself, but if you think there is, you should take it up with
the PostGIS authors; there may be a need to adjust the way PostGIS is
packaged into an extension.
