The PostgreSQL user you are connecting with must have permission to create tables and triggers.
When performing synchronization repeatedly, Skyvia synchronizes only data that was changed since the previous synchronization. It uses the fields storing information about when a record was created and modified in cloud applications and creates special tracking tables and triggers in relational databases for data modification tracking. The "*_tracking_store" table is created in the database while performing initial synchronization and contains information about changes in the corresponding PostgreSQL tables before the next synchronization.
Feel free to ask any further questions.
