[Spacewalk-list] Please help with Oracle -> PostgreSQL migration

[James Fillman]

The postgreSQL import stage of the migration is failing on me.



It bombs out with this error message:



ERROR:  invalid byte sequence for encoding "UTF8": 0xeda080

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 rhnpackagechangelogdata, line 136452



I found a posting from July where someone had a similar problem. You had him apply a patch to the spacewalk-dump-schema script. I went to apply the same patch and found it to already be there.



Here's a snippit from that old post:

Can you apply the following patch to your spacewalk-dump-schema and dump and import the schema again, to see if it addresses the problem for you?



diff --git a/utils/spacewalk-dump-schema b/utils/spacewalk-dump-schema index e391111..0068ed4 100755

The patch apparently worked for the other guy. When I check the oracle dump, I find the same 'Types' line:



-- Types for rhnpackagerepodata: DOUBLE PRECISION BLOB BLOB BLOB DATE DATE copy rhnpackagerepodata(package_id,primary_xml,filelist,other,created,modified) from stdin;



Any idea's?



Since I have to scheduled downtime in advance, it's taking me a while to try out your suggestions and make any progress. I appreciated the quickness of your previous responses.



Cheers,
