Comment(by aperi2007):

 Hi,

 The postgres guy find where the postgres crash.

 ( http://archives.postgresql.org/pgsql-bugs/2010-10/msg00042.php)

 >It's crashing in pfree, as called by examine_attribute here:

 >               pfree(stats);
 >               return NULL;

 do the >logs show analysis beginning, but onerel->rd_rel->relname is
 "suolo". At the time >of the crash it seems to have already added the
 column with attr->attname = >"codpoligono" to vacattrstats and is
 examining the column with attnum=5 when it >crashes. A quick look at
 pg_class and pg_attribute shows that this is (surprise!) >the "geom"
 column of type "geometry".

 They ask if there some relation with a last-minute correction of
 postgres).
