Обсуждение: Migrate postgres databases from SQL_ASCII to UNICODE encoding
A simple question, we need to migrate many (>20) postgres databases from SQL_ASCII encoding to UNICODE encoding, over a 7.3.6 server.
With Dump/Restore , we get an error (Invalid Unicode) in any field that has a 8 bits character coming from the SQL_ASCII , even setting the client_encoding to WIN, ISO-8859-1, and others encodings.
I'm really worried about this problem since , we have many DBs to migrate and even with a ODBC program we can't port tables from Postgresql/SQL_ASCII to Postgresql/UNICODE.
Any suggestion will be *very* appreciated.
Regards,
Dario.

SQL_ASCII is not an encoding (it's more like the absence of knowledge about an encoding). What is the data actually stored as? > With Dump/Restore , we get an error (Invalid Unicode) in any field that > has a 8 bits character coming from the SQL_ASCII , even setting the > client_encoding to WIN, ISO-8859-1, and others encodings. It might work to just UPDATE pg_database to set datencoding to the correct value reflecting what you have actually stored. You might then need to REINDEX any indexes on textual columns, but I don't think anything else would go wrong. If you have a mishmash of different encodings in a single database, then of course there is no simple solution; you are in for some pain while you try to fix the data. regards, tom lane
