Hi,

- From the documentation, length(string) is 'Number of characters in string'

But it didn't :

1/ in a LATIN9 database:

postgres=# show server_encoding;
server_encoding
- -----------------
LATIN9

postgres=# set client_encoding = utf8;
SET
postgres=# select length('é');
length
- --------
1

postgres=# set client_encoding = latin9;
SET
postgres=# select length('é');
length
- --------
2

2/ in a UTF8 database:

postgres=# show server_encoding;
server_encoding
- -----------------
UTF8

postgres=# set client_encoding = utf8;
SET
postgres=# select length('é');
length
- --------
1

postgres=# set client_encoding = latin9;
SET
postgres=# select length('é');
length
- --------
2
