If you are running Windows 7, you are likely maintaining legacy software.
If you try to use the standard Unicode driver with these old apps, you’ll likely see garbled text ( ???? ), truncated strings, or the driver simply failing to appear in the ODBC Data Source Administrator list.
If you are setting up a new connection in 2026, consider using the PostgreSQL Unicode driver with a small shim application if possible. However, if you are stuck with an ANSI-only app, the psqlODBC ANSI driver is your hero. postgresql ansi odbc driver windows 7
(It does exactly what it is designed to do, but what it is designed to do is largely obsolete for modern database connectivity.)
Functional but Legacy. Unless your specific application requires ANSI encoding (common in older accounting software or legacy VB6/Access apps), you should use the Unicode driver instead. If you are running Windows 7, you are
To get started, download the PostgreSQL ODBC driver from the official PostgreSQL website. You can choose from various versions, including the ANSI driver. For this post, we'll use the PostgreSQL 13 ODBC driver.
The standard solution is the PostgreSQL ODBC driver (psqlODBC). However, many users run into a specific hurdle: . If your legacy application doesn't understand Unicode, the standard 64-bit driver won't work. You need the PostgreSQL ANSI ODBC Driver . If you are setting up a new connection
