Ok, I got false understanding that REPLICA IDENTITY is used for
something more than a WAL. This is basically not true. So, what I can
do
* Set the REPLICA IDENTITY to full, and in this case I can still get
the pk from rd_pkindex. In this case the WAL will be bigger, but we
will have all the values in it.
* Other solution is basically (since we know exact primary key) - get
the row, and take the latest value from there using SQL query on the
client side (other part of kafka)
Thank you very much fro your help
