OK - that way around just gets the NOTICE

psql:./huge.db:11: NOTICE: SYSID can no longer be specified

- fair enough.

BTW there was an earlier thread about plpgsql validation. The aforementioned
8.1devel database has a long history and createlang was run against an
early 7 incarnation, with pg_dumpall -> new database all the way to the
present. I tried the fix mentioned in the earlier message to encourage
validation. Now dumping this "fixed" database, and loadinging it into the
new database gives:

ALTER FUNCTION
psql:./huge.db:4403: ERROR: function plpgsql_validator(oid) does not exist
CREATE FUNCTION
ALTER FUNCTION
psql:./huge.db:4517: ERROR: language "plpgsql" does not exist
HINT: You need to use "createlang" to load the language into the database.

now to unfix the fix...
