Re: BUG #18310: Some SQL commands fail to process duplicate objects with error: tuple already updated by self

Hi Tender Wang,

I think your code changes *LGTM*. Thanks for your contribution.

But I meet these errors when I git apply your patch, so I do some tiny
formate modification.
Please refer to the patch which is still authored by you.

``` bash
$ git apply 0001-Fix-reporting-error-when-process-duplicate-token-typ.patch
0001-Fix-reporting-error-when-process-duplicate-token-typ.patch:38: indent
with spaces.
    List       *tokennames = stmt->tokentype;
0001-Fix-reporting-error-when-process-duplicate-token-typ.patch:73: indent
with spaces.
        {
0001-Fix-reporting-error-when-process-duplicate-token-typ.patch:74: indent
with spaces.
            if (!stmt->missing_ok)
0001-Fix-reporting-error-when-process-duplicate-token-typ.patch:75: indent
with spaces.
                ereport(ERROR,
0001-Fix-reporting-error-when-process-duplicate-token-typ.patch:76: indent
with spaces.
                        (errcode(ERRCODE_INVALID_PARAMETER_VALUE),
warning: squelched 9 whitespace errors
warning: 14 lines add whitespace errors.
