PostgreSQL 使用 \copy 命令时报 character with byte sequence 0xc3 0xa5 in encoding "UTF8" has no equivalent in encoding "GBK"

错误信息

ERROR:  character with byte sequence 0xc3 0xa5 in encoding "UTF8" has no equivalent in encoding "GBK"

解决方法

导出时指定encoding为utf8

\copy (select * from test_table) to 'C:/data.csv' (FORMAT 'csv', DELIMITER ',', HEADER true, NULL 'UNKOWN', ENCODING 'UTF8')
