[Question] Generate Record from Record subset of keys?

Hi guys!

Really great library, well done and hats off to you.

Just a small question: can I generate a Record from a subset of another Record's keys? e.g.:

record: Record = conn.fetchrow(query, foo)
print(len(record.keys()) # let's say there are 10 keys

# Make a new Record from the first 8 keys
new_record = Record(record[:8])

The reason I can't just cast the original Record to a dict is because it was generated using 2 INNER JOINs onto the same table, and so I have non-unique column descriptions in the result from that query.

从 asyncpg 的 Record API 和示例中描述的 conn.fetchrow 结果开始；issue 未指明源文件或测试。确定是否支持从键的子集构造 Record，并明确对于包含重复列名的结果所支持的方法。
