**Describe the situation**
https://markify.dev/p/zfrQMV2/text

**How to reproduce**
On aws `c5ad.24xlarge` run a query:

```
SET max_memory_usage = '100G', max_threads = 1000, max_insert_threads = 96

INSERT INTO wikistat WITH
    parseDateTimeBestEffort(extract(toLowCardinality(_path), 'pageviews-([\\d\\-]+)\\.gz$')) AS time,
    splitByChar(' ', line) AS values,
    splitByChar('.', values[1]) AS projects
SELECT
    time,
    projects[1] AS project,
    projects[2] AS subproject,
    values[2] AS path,
    CAST(values[3], 'UInt64') AS hits
FROM s3('https://....s3.eu-central-1.amazonaws.com/wikistat/original/*.gz', '...', '...', LineAsString, auto)
WHERE length(values) >= 3
```

Performance is not bad (22 million rows are inserted per second) but can be better.
{
    bool first = true;
    assertChar('[', buf);
    while (!buf.eof() && *buf.position() != ']')
    {
        if (!first)
        {
            if (*buf.position() == ',')
                ++buf.position();
            else
                throw ParsingException("Cannot read array from text", ErrorCodes::CANNOT_READ_ARRAY_FROM_TEXT);
        }
        first = false;
        x.push_back(T());
        readQuoted(x.back(), buf);
    }
    assertChar(']', buf);
}
template <typename T>
void readDoubleQuoted(std::vector<T> & x, ReadBuffer & buf)
