Obviously noone has ever tested the doubling of availiable result ids

Obviously noone has ever tested the doubling of availiable result ids
up to
reaching the hard limit. After opening 16(=current REST_START value)
results via pg_exec, the next pg_exec tries to find an empty slot
forever :-( . In PgSetResultId file pgtclId.c in the for loop there
has to be done a break, if res_max ist reached. The piece of code
should look like
        if (resid == connid->res_max)
        {
            resid = 0;
            break;   /* the break as to be added */
        }

now everything works (double available results after reaching
RES_START up to reaching RES_HARD_MAX)
