Yes.. this could be the point!!!!!
In fact I do not face problems when a execute a select using similar
tables (also larger than those I described in the previous e-mail) but
containing POINTS instead of POLYGONS
I suppose that for the points (that are short) postgresql do not use
TOAST tables. On the contrary postgres use TOAST table with the polygons
(that are long).
Can you suggest a workaround to solve this problem?
Should I ask to the PostGIS user mailing list?
Best regards,
Ivan
