Re: replication topography

Hello Steve,

Thanks a lot for your info yesterday, it was very useful. If I run this command on some of the servers and the results look like this, what would it tell you?

select * from pg_extension  ;
   extname    | extowner | extnamespace | extrelocatable | extversion | extconfig | extcondition
--------------+----------+--------------+----------------+------------+-----------+--------------
 plpgsql      |       10 |           11 | f              | 1.0        |           |
 postgres_fdw |       10 |         2200 | t              | 1.0        |           |

postgres=# select * from pg_extension  ;
 extname | extowner | extnamespace | extrelocatable | extversion | extconfig | extcondition
---------+----------+--------------+----------------+------------+-----------+--------------
 plpgsql |       10 |           11 | f              | 1.0        |           |
(1 row)

I understood it is slony, the rest I need to find from hba file?
