Hi, ALL,

In the docs I see the following:

[quote]

PGresult *PQexecParams(PGconn *conn,
                       const char *command,
                       int nParams,
                       const Oid *paramTypes,
                       const char * const *paramValues,
                       const int *paramLengths,
                       const int *paramFormats,
                       int resultFormat);
[/quote]

Is there a reason why the parameters are int and not unsigned int?

There is no way the length can be negative...

Is it for backward compatibility?

Thank you.
