Обсуждение: pg_restore errors

Hi List;

Trying to restore a pg_dump I get this:

pg_restore: ERROR:  invalid byte sequence for encoding "UTF8": 0xae
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".
CONTEXT:  COPY imm_lookup, line 2
pg_restore: [archiver (db)] error returned by PQendcopy: ERROR:  invalid byte
sequence for encoding "UTF8": 0xae
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".
CONTEXT:  COPY imm_lookup, line 2


This is a dump file that was handed to me from a client. I don't know anything
about what the dump flags were or what the db encoding was. Is there a way to
find out (I'm assuming this is an encoding mis-match) from the dump file.

I did do a pg_restore -l and got this:

Any thoughts?

Thanks in advance..

I had a similar issue a week or 2 ago - turns out my original database was
using SQL_ASCII encoding, not UTF-8.

Can your client tell you what encoding they're using? Otherwise, just try a
few different ones. Someone else might have a tricky way to work out what
the encoding should be based on the dump (but I don't ;))

Cheers,

Well, the fact that you got that message says that the original database
was, or thought it was, in UTF8 encoding: pg_dump would have propagated
that fact into a "set client_encoding" command in the dump script.

I suppose that this data got loaded into the database while it was being
run by one of the early 8.1.x releases that didn't check encoding very
carefully :-(.  You're going to have to guess what the real encoding is;
querying the client about his typical locale settings might help.

When trying to fix up the data, keep in mind that what you have now is
likely a mix of real UTF8 and whatever-this-is.
