Обсуждение: Character encoding conversion

I have a database which was originally created with LATIN1 encoding.
I'd like to move it to UTF8.  The data will load ok (COPY)  but I am
getting 'invalid byte sequence for encoding..." messages when accessing
the data.

Is there a way to automatically convert the offending characters, or to
easily locate them in a pg_dump file so they can be converted by hand?

Try using 'iconv' for your dump file and convert it all to UTF8 first before restoring to a UTF8 database.

What's the complete error message?  What's the output of the following
query in a session that gets the error?

select name, setting from pg_settings where name ~ 'encoding';

You said the data loaded without error, right?  Let's see if we can
figure out why queries are failing before considering what corrective
action to take.

How exactly did you move the data?  And what PG version are we talking
about?

If you've got client_encoding and server_encoding set up correctly,
it should happen automatically during the COPY.  I think you messed
that up somehow, but it's not clear just how.
