what should happen in this case?

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: https://www.2ndquadrant.com/en/resources/pglogical/
your problem seems as a typical task for logical replication to me. You needs 9.4 at least.
