Using psycopg2 (Python), pg-promise (Node.js), or any JDBC driver, establish a secure connection to your database.

| Approach | Pros | Cons | |----------|------|------| | Custom Python script | Full control, free | Requires maintenance | | Zapier / Make | No-code, fast | Costly at scale | | Estuary Flow / Airbyte | CDC, schema evolution | Overhead for simple use | | dbt + Dropbox external stage | ELT-ready | Requires cloud storage bridge |

import dropbox import psycopg2 dbx = dropbox.Dropbox("YOUR_TOKEN") conn = psycopg2.connect("dbname=test user=postgres")

for entry in dbx.files_list_folder("/data").entries: if entry.name.endswith(".csv"): meta, res = dbx.files_download(entry.path_lower) # Load into PostgreSQL using COPY with conn.cursor() as cur: cur.copy_expert("COPY my_table FROM STDIN CSV HEADER", res.content) conn.commit() Use Case: Automating ETL from Dropbox to PostgreSQL
