As the thread indicates, I am using DB2 Linux.
I used Carto one with ODBC and it is just not production ready. Found two bugs within days of

I am currently using Unix pipes to export data from DB2 and concurrently load it to PG via COPY.
It saves nearly half the time of exporting first to file and then loading it.
