Log message:
    Repair problem identified by Olivier Prenant: ALTER DATABASE SET search_path
    should not be too eager to reject paths involving unknown schemas, since
    it can't really tell whether the schemas exist in the target database.
    (Also, when reading pg_dumpall output, it could be that the schemas
    don't exist yet, but eventually will.)  ALTER USER SET has a similar issue.
    So, reduce the normal ERROR to a NOTICE when checking search_path values
    for these commands.  Supporting this requires changing the API for GUC
    assign_hook functions, which causes the patch to touch a lot of places,
    but the changes are conceptually trivial.
