Hi,
I've prepared a patch[1] which makes it possible to use composite formats
in query results.
It defines
PQexecParams() PQexecPrepared() PQsendQueryParams() PQsendPrepared()
functions with last
int resultFormat
parameter replaced with
int nResFormat, const int resParamFormats
Therefore, it breaks compatibility with the existing PQ*Params() and
PQ*Prepared() functions. (Use at your own risk.)
There's also a test case[2] too

Any comments will be appreciated.
Regards.
