Re: PQfformat() and Composite Formatted Results

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.
