That's not a valid byte sequence for a character under the UTF8
character encoding scheme.  You said that PostgreSQL is using utf-8,
but what encoding is used for the report?  Is your client connecting
using the character encoding scheme used by the report?

Hi there,
I am trying to find any kind of information or examples to deal with
custom conflict resolution on swap syncs in a master-master replication.

Any clue will be very wellcome,

Thanks in advance,

Amador A.

What are you using for replication?

Hi Kevin,

I set up a master-master asynchronous replication of one database with bucardo 4.4.5 and testing right now 4.99.3.
I know the standard settings when a conflict between same id rows comes up :

source - the rows on the "source" database always "win" (in a conflict, we copy rows from source to target)


target - the rows on the "target" database always win


skip - any conflicted rows are simply not replicated. Not recommended
for most cases.


random - each database has an equal chance of winning each time


latest - the row that was most recently changed wins


abort - the sync is aborted on a conflict You can also provide custom
conflict handlers to allow you to use business logic for better conflict
resolution.


I have not found info or examples about the custom option yet, and still on the search ...

Cheers,

Amador A.
