[SQLGRASS] d.what.s.pg

[javier garcia - CEBAS]

Hello.

d.what.s.pg gives an error, and I woul like to know if it is my fault in some 
way.
My Postgres table is:

 cod_grass |  xutm  |  yutm   | codigo | tipo | red  | nombre |  status
-----------+--------+---------+--------+------+------+-------------------------------+-----------
1 | 631990 | 4209110 | 01002  | A    | CHS  | RIO PLIEGO  |Operativo
2 | 643680 | 4210660 | 01003  | A    | CHS  | RIO MULA| Operativo
3 | 652390 | 4206450 | 01004  | A    | CHS  | RBA. SALADA |Operativo
4 | 661830 | 4201470 | 01005  | A    | CHS  | EL REGUERON | Operativo
...
And I would like to query all the attributes, by clicking on a grass monitor.
So, I, ve prepared a file called "grass_query.sql":

SELECT * FROM redhidro WHERE point(xutm,yutm);

And, I've used:
GRASS:> d.what.s.pg -s sql=grass_query.sql distance=100

But when I click on the map I obtain:
Buttons:
Left:  Select site for DB query.
Right: Finish.
-----------------------
Executing
SELECT * FROM redhidro WHERE point(xutm,yutm);
 @ '(661633.204134,4192394.186047,661833.204134,4192594.186047)'::box;
 clause  @ '( )'::box addded automatically.

Error: Connecting to Postgres:ERROR:  parser: parse error at or near "@"
-----------------------------------

Is this my fault or a GRASS error?

Thanks for your answers,
best regards,

Javier
