Desired behavior is to just log the error and continue the import using

Each COPY is atomic so if any part of it fails the whole thing fails, so
you will not be able to achieve what you want that way.
The servers are not on the same network. Sneaker net is the only way

Other solution:
* create the tables on the destination server without the PK or with an
other, new PK (maybe SERIAL)
* use logical replication to replicate the table from all your
source-db's to the destination table, see more here:

your problem seems as a typical task for logical replication to me. You
needs 9.4 at least.
