Hi,

when trying to run pg_dumpall it fails with the above mentioned error.

The last lines of the output looks like this:

QUOTE START ------

--
-- Database creation
--

pg_dumpall: query failed: ERROR:  unrecognized node type: 650
pg_dumpall: query was: SELECT datname, coalesce(rolname, (select rolname
from pg_authid where oid=(select datdba from pg_database where
datname='template0'))), pg_encoding_to_char(d.encoding), datcollate,
datctype, datfrozenxid, datistemplate, datacl, datconnlimit, (SELECT spcname
FROM pg_tablespace t WHERE t.oid = d.dattablespace) AS dattablespace FROM
pg_database d LEFT JOIN pg_authid u ON (datdba = u.oid) WHERE datallowconn
ORDER BY 1

QUOTE END ---

What can I do to be able to unload the data again?

Regards Wilfried
