The original database (which is created with SQL_ASCII) contains invalid byte sequences in some columns (target database created with UNICODE): jkr@Panoramix:~/postgresql$ pg_dump -t artik munttest | psql muntfinal > output.txt ERROR: invalid byte sequence for encoding "UNICODE": 0xeb207a CONTEXT: COPY artik, line 11705, column omschrijving: "Anna v. Groot Brittannië zi prf 38.61 mm" So I cannot dump/restore/alter table. I was hoping that piping the text from stdout to psql that a valid conversion to unicode would take place but apparently that is not the case. Any other ideas?
