Re: Is there public API to fetch errcode?

sqlstate is saved into conn->last_sqlstate along with the error message
in pqGetErrorNotice3:

         if (id == PG_DIAG_SQLSTATE)
             strlcpy(conn->last_sqlstate, workBuf.data,
                     sizeof(conn->last_sqlstate));

is this usable? Can it be extracted somehow?
