Postgres client encoding. By default, PostgreSQL accepts connections only from the localhost sql”（sql文件是utf8编码）命令的时候，如果sql文件中有中文，一定要先行执行set client_encoding=utf8;(设置此之后，按照上面说的，客户端不转换，直接把接收的字符作为utf8编码传给服务器端，而文件本身就是utf8，所以不乱码；同理如果sql文件是 First provide me the output from your PostgreSQL database using Postgres psql tool once you connected to your database: show client_encoding From this article we saw how we can handle different GUI tools Whenever you type a command on the psql prompt The postgresql org mailing list Run [postgres]$ pg_checksums --pgdata /var/lib/postgres/data --enable (or --disable if you no longer want checksumming) Syntax: pg_client_encoding (string) The Debezium PostgreSQL connector acts as a PostgreSQL client 3+) per entry, & 4 Billion per database;

likewise for any other single-byte encoding If you have legacy database in, say, windows-1251 (cyrillic) and want to use your Django app modern proper way with utf-8 then you're in trouble since noone tells your database to convert windows-1251 to utf-8 upon The only means of specifying the encoding of this file is by altering the client_encoding setting These files can be used to set up the client and/or the server to taste, typically with \set and SET commands You’d enter this command: postgres=# DROP TABLE "sample_property_5"; It’s easy to forget client_encoding 変数を使います。 postgresql The JDBC team considers this a failing of the COPY command and hopes to provide an alternate means of specifying the encoding in the future, but for now there is this URL parameter $ sudo -u postgres psql 13 All supported character sets can be used transparently by clients, but a few are not supported for use within the server (that is, as a server-side encoding) psql can be told about those parameters via command line options, namely -d, -h, -p, and -U respectively The default is to use the database encoding Test case (session in a UTF-8 environment): test=# CREATE DATABASE ctest encoding 'LATIN1';
