    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.

      Unsigned ints are, I believe, less performant, and losing half the value
      space is immaterial here.
