Hi, thx for response.

>Does that include PostGIS datatypes?

yes, but after some email with the guys of Posgis team , I think the problem
is related to postgres.

(see this thread on postgis ML):
http://postgis.refractions.net/pipermail/postgis-users/2010-October/027841.html

The postgis team was using a my script sql (about 10mbyte, 1Mb compress)
that always crash a PG9 32bit on windows7 64 bit.

Using that script and setting the verbosity as Postgis team suggest I see
this report:

If you like I can send you the script.
It create may tables and start to populate using many inserts.

The real script is more big then this, but this 10mbytes is sufficient to
crash PG9.

However the main table involved is this:
