Hi, my POC in postgres 12.(important ?)
if I setup 2 postgres clusters, and create a publication in one and a subscription in the other, and do on the pub an update which does not change the data (updating an existing record with same data) then this (useless) update go through replication.(ie consumes network ressource) what are ways to avoid this ? (I thought of a trigger to not execute the useless update, but I dont see how to do this) any ideas ? thanks PS: remarks about the meaning of this are off topic, thanks Marc MILLAS Senior Architect +33607850334 www.mokadb.com
