查看pg客户端字符编码:
show client_encoding
查看pg服务端字符编码:
show server_encoding
Postgresql [ERROR: invalid byte sequence for encoding "UTF8": 0xc0ee]
原因是没有正确设置客户端字符集。
默认情况下,Postgresql是不转换字符集的,如果你的数据库是UTF8的字符集,一般终端的中文字符集会设置为GBK,或en_US(查看终端的字符集可以看LANG环境变量的设置),所以你输入的中文是GBK的编码,这个编码不经转换的存入数据库中,而数据库是UTF8的,Postgresql一看没有这样的UTF8编码,所以当然报错了。
【解决方法】:
方法二:直接设置终端的字符集编码为UTF8,让输入的编码直接为UTF8,而不是GBK。
【具体演示】:
设置postgresql的客户端编码:
设置psql客户端字符集为GBK,方法有两种,一种是在psql中输入“\encoding GBK” ,另一种是设置环境变量“export PGCLIENTENCODING=GBK”,演示如下:
#psql -d dsc
dsc=# insert into t values(1,'中国');
ERROR: invalid byte sequence for encoding "UTF8": 0xd6d0
HINT: This error can also happen if the byte sequence does not match the encoding expected by the server,which is controlled by "client_encoding".
dsc=# show client_encoding;
client_encoding
-----------------
UTF8

#psql -d dsc
dsc=# insert into t values(1,'中国');
ERROR: invalid byte sequence for encoding "UTF8": 0xd6d0
