如何格式化(CSV？)文本文件,以便可以将其导入(使用COPY？)到Postgresql(8.4)表中的数组列中？
给出表testarray：
Column | Type | ---------+-------------------------| rundate | date | runtype | integer | raw | double precision[] | labels | character varying(16)[] | results | double precision[] | outcome | character varying(8)[] |
和
COPY testarray from '/tmp/import.txt' CSV
import.txt的以下内容都不起作用：
2010/06/22,88,{{1,2},{3,4}},4}}
2010/06/22,1,2,3,4,4
2010/06/22,'{{1,4}}',4}}'
2010/06/22,'1,4',4'
COPY testarray from '/tmp/import.txt' CSV
2010-06-22,"{{1,4}}",4}}"
