Why is 0 returned in PQcmdTuples?

Hi,

I know it's documented that CREATE TABLE ... AS SELECT ...
and SELECT ... INTO TEMP ... returns "0" as number of
affected tuples via PQcmdTuples().

Why?
How much work would it be to pass this info up?

The question arose because in ECPG, such statements
like the above returns 0 in sqlca.sqlerrd[2], but Informix
returns the number of tuples copied.

Best regards,
