Hi,

 

I have a database in SQL_ASCII Encoding format from Postgresql-7.4.19.  I have migrated to Postgresql-8.4.9 and to UTF-8 and want to restore this database in UTF-8 encoding.  I am facing problem in restoring it as UTF-8.  I have 29 tables in the database, out of which it is unable to restore 3 tables.  It gives the following error:

 

pg_restore: [archiver (db)] Error while PROCESSING TOC:

pg_restore: [archiver (db)] Error from TOC entry 83; 0 40257 TABLE DATA document postgres

pg_restore: [archiver (db)] COPY failed for table "document": ERROR:  invalid byte sequence for encoding "UTF8": 0xe92034

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 document, line 15

pg_restore: [archiver (db)] Error from TOC entry 88; 0 40271 TABLE DATA attribute postgres

pg_restore: [archiver (db)] COPY failed for table "attribute": ERROR:  invalid byte sequence for encoding "UTF8": 0xe90931

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 attribute, line 909

pg_restore: [archiver (db)] Error from TOC entry 90; 0 40277 TABLE DATA revision_state postgres

pg_restore: [archiver (db)] COPY failed for table "revision_state": ERROR:  invalid byte sequence for encoding "UTF8": 0xe9e96e

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 revision_state, line 363

 

I have checked these three tables and I found that these tables contain special characters as values for some attributes for some records.  I tried to use the procedure mentioned in the following link, which didn’t worked for me:

I also have blobs in one table in this database, but I don’t think/see any issues with them.  Is there a way to restore the database from SQL_ASCII to UTF-8?  Is there a way to restore the database as SQL_ASCII and then convert the Encoding to UTF-8?  What is the consistency level?  Or are there chances of getting garbage?

 

Kind Regards,

Manoj Agarwal
