Tonton,
This is a limitation of shapefiles .dbf format. (yet another reason to move
away from shapefiles). PostGIS can't assume that your value is a categorical
value (ie a label) when the column only contains numbers and is tagged as
numeric. To allow for the widest range of cases, it is imported probably as
float or numeric, so if all your column values are integer you could easily
(post-import) issue :
ALTER TABLE ltb ALTER COLUMN annoying_column TYPE int USING
cast(annoying_column as int);
hth.
cheers
