数组 – 将数据COPY(导入)到PostgreSQL数组列中

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}}"
