Hi 

Here it is a scenario which I am faced with  and I am hoping to find a 
pointer/tip/help

db1 is the OLTP system
db2 is the Reporting system

The data from db1 needs to get to db2, but the database on those two have 
tables with different layout/structure and hence data will need to suffer some 
transformation in between in real time

I was looking at something like 

db1 -> db2 replicates the same set of tables and with the same structures using 
pglogical for example 
db2.tbl1 -> db2.tbl2 data gets massages/transformed based on what replicates 
from db1.tbl1 using triggers and functions


Other than that I reckon db1 -> db2 would be trigger based using something like 
slonik maybe (?) and data massage/transformation gets moved from db2 to db1 
machine and then db1.tbl2 -> db2.tbl2 using pglogical 


Is this doable ? If so any pointers as to where to look about it ?


Many thanks
Armand
