The PostgreSQL ODBC driver is fast, but it adds a thin layer of overhead. For a modern microservice, use the native pq (Go) or asyncpg (Python). But for a one-off data import from a 20-year-old VB6 application into Postgres? The ODBC driver is your only option—and it works surprisingly well.

Maintained by the PostgreSQL community (and currently hosted on the pgFoundry archive), psqlODBC is stable and mature. It supports advanced features like SSL encryption, Kerberos authentication, and even COPY (bulk transfer) protocols for high-speed inserts.
