Обсуждение: ANALYZE errors (postgres 8.1.4)

I'm having some problems with ANALYZE.

When I run ANALYZE on a postgis enabled database created by ogr2ogr from
the Census Bureau's tiger data I get the following error for a number of
the tables created:


tiger2005se=# ANALYZE arealandmarks ;
NOTICE:   no notnull values, invalid stats

I can't find any reference to this error.  What does it mean?

Table structure:
tiger2005se=# \d arealandmarks
                                  Table "public.arealandmarks"
    Column    |     Type      |                            Modifiers
--------------+---------------+-----------------------------------------------------------------
 ogc_fid      | integer       | not null default
nextval('arealandmarks_ogc_fid_seq'::regclass)
 wkb_geometry | geometry      |

Indexes:
    "indx_mod_arealandmarks" btree (module)
Check constraints:
    "enforce_dims_wkb_geometry" CHECK (ndims(wkb_geometry) = 2)

You'd have to ask the PostGIS people --- there is no such error message
in the base Postgres distribution, so I suppose it must be theirs.

Yes, this is a PostGIS message.

Thanks Tom & Michael,

Now I know where it comes from I can deal with it sensibly.
