there will be an integer overflow issue?

Can you try the following?

static int64
defGetCopyRejectLimitOptions(DefElem *def)
{
    int64                    reject_limit;
    reject_limit = defGetInt64(def);
    if (reject_limit <= 0)
        ereport(ERROR,
            (errcode(ERRCODE_INVALID_PARAMETER_VALUE),
                errmsg("REJECT_LIMIT (%lld) must be greater than zero",
                    (long long) reject_limit)));
}




REJECT_LIMIT <replaceable class="parameter">integer</replaceable>
i think, you want REJECT_LIMIT be bigint?
so here it should be
REJECT_LIMIT <replaceable class="parameter">bigint</replaceable>\
?
