I debugged index with gdb and  found that it is segmentation fault in my
procedure named *gist_mov_consistent* it is only 7 lines. So I think it is
worth to publish it to public,

*
* *Datum gist_mov_consistent(PG_FUNCTION_ARGS)*
*{*
*    GISTENTRY *entry = (GISTENTRY *)PG_GETARG_POINTER(0);*
*    BOX *query = PG_GETARG_BOX_P(1);*
*    StrategyNumber strategy = (StrategyNumber)PG_GETARG_UINT16(2);*
*    *
*    if (DatumGetMovP(entry->key) == NULL || query == NULL)*
*        PG_RETURN_BOOL(FALSE);*
*    *
*    PG_RETURN_BOOL(obj_contains(DatumGetMovP(entry->key), query));*
*}*

Do you have any ideas where is the problem ? :)

Best regards,
