[PostgreSQL Unicode] Description = PostgreSQL ODBC driver (Unicode) Driver = /usr/lib/x86_64-linux-gnu/odbc/psqlodbca.so Setup = /usr/lib/x86_64-linux-gnu/odbc/libodbcpsqlS.so Driver64 = /usr/lib/x86_64-linux-gnu/odbc/psqlodbcw.so Setup64 = /usr/lib/x86_64-linux-gnu/odbc/libodbcpsqlS.so FileUsage = 1 The PostgreSQL ODBC driver ( psqlODBC ) is a battle-tested, production-grade bridge that effectively maps PostgreSQL’s rich type system and protocol to the rigid, 1990s-era ODBC specification. It excels at enabling legacy BI tools and Microsoft Office integration but reveals its age in async handling, timezone semantics, and cursor emulation. odbc postgresql driver

| Variant | Target | Unicode | Threading | Notes | |---------|--------|---------|-----------|-------| | | Legacy apps (ASCII) | No – uses char | Safe | For old VB6, Delphi, or Access 97. | | Unicode | Modern apps (UTF-16/8) | Yes – uses SQLWCHAR | Safe | Recommended for all new development. | [pg_production] Driver = PostgreSQL Unicode Server = 10

: 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 ): | | Unicode | Modern apps (UTF-16/8) |

| Alternative | Protocol | Pros | Cons | |-------------|----------|------|------| | (Go) + PGX ODBC bridge | Custom | Type-safe, fast | Not ODBC | | Npgsql (.NET) | Native .NET | Async, NodaTime support | Only .NET | | PostgreSQL FDW + ODBC FDW | SQL/MED | Pushdown | Complex | | ADBC (Arrow Database Connectivity) | Columnar | Zero-copy | Very new |

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.
