Hi.

The Slony maintenace docs recommend disabling PostgreSQL autovacuum
on the Slony tables (http://www.slony.info/documentation/maintenance.html)
but the command to identify the tables fails:

mycluster# select oid, relname from pg_class where relnamespace =
(select oid from pg_namespace where nspname = '_' || 'MyCluster') and
relhasindex;
...
ERROR:  column "_" does not exist
LINE 1: ...e = (select oid from pg_namespace where nspname = _ || ...

Has this command changed for 8.4.4 ?  (I'm running slony 1.2.20
against PostgreSQL 8.4.4.)

Best,
