We can change database encoding values for postgresql database by using following steps but make sure that you have taken backup for current database.
Log in to server as root user and switch to postgres
su postgres –
To check all database run
psql -l
To switch database for example we are using support_test
psql -d support_test
Run command to check encoding
SET CLIENT_ENCODING TO ‘LATIN1’;
or
SET NAMES ‘LATIN1’;
Now check encoding
support_test=# SHOW client_encoding;
client_encoding
—————–
LATIN1
(1 row)
