Hi Ron,

I can not reproduce this error on BDR_Node_2 (it is not BDR_Node_1 as
stated before. Typo)

I've been successful in transferring the data with pg_dump on BDR_Node_2
and then restoring it on Regular_Node_1. Then running "select * from
information_schema.sequences;" all is OK.

The problem with this approach is that I'm required to have minimal
downtime in this transition and we have a lot of data to transfer, which
would be lengthy process.

Thank you in advance.
Best regards, Janis Puris

1. Are you sure that you removed all BDR from the node?
2. Is the corruption there in BDR_Node_1?
3. Can you rebuild the indexes?
