[postgis-users] operator does not exist

[Denis Rouzaud]

Hi,

When using pg_restore, I get this error:

pg_restore: [archiver (db)] could not execute query: ERROR: operator 
does not exist: public.geometry && public.geometry
LINE 1: SELECT $1 && $2 AND _ST_Overlaps($1,$2)

I don't understand since \do && returns:
  public     | &&   | geometry      | geometry       | boolean     |

I just did install pg 9.3 + postgis 2.1 on a server and trying to use 
dumps from pg 9.1 + postgis 2.0.

Any idea?

Thanks a lot!

Denis
