I’m using python and psycopg2 to remotely query some psql databases, and I’m trying to figure out the best way to select the data I need from the remote table, and insert it into a table on a separate DB (local application server).

    COPY isn’t limited to tables, you can use a query as the source as well, check out the examples in the manual, it shows how to use COPY to create a text file based on a query:
