: The ANSI driver is effectively dead. Microsoft has deprecated ANSI ODBC APIs. Use the Unicode driver even for legacy ASCII data – the driver converts correctly. 10. Configuration Example for Production A well-tuned DSN entry ( /etc/odbc.ini ):

It excels at enabling legacy BI tools and Microsoft Office integration but reveals its age in async handling, timezone semantics, and cursor emulation. For greenfield projects, native drivers (e
For greenfield projects, native drivers (e.g., Npgsql , pgx , asyncpg ) are superior. However, when the requirement is “connect Tableau to PostgreSQL over ODBC,” psqlODBC remains the correct, stable choice – provided you tune the 5–10 critical parameters and avoid its known pitfalls around timestamptz and scrollable cursors.
