psqlodbc2 — PostgreSQL ODBC Driver

A ground-up, modern C11 rewrite of the PostgreSQL ODBC driver, designed as a drop-in replacement for the original psqlodbc. It builds with Meson and runs on Linux, macOS, and Windows.

• Version: 0.1.0
• Language: C11
• Driver library: libpsqlodbc2w.so / libpsqlodbc2w.dylib / psqlodbc2w.dll
• ODBC driver name: PostgreSQL ODBC Driver (psqlodbc2)
• Compatibility: passes the upstream psqlodbc regression suite (parity target).

Quickstart (build from source)

meson setup builddir          # configure
meson compile -C builddir     # build
meson test -C builddir         # run tests

The driver is produced under builddir/src/. On macOS, prefix meson setup with PKG_CONFIG_PATH=/opt/homebrew/opt/libpq/lib/pkgconfig. See the build guide for platform details.

Once installed and registered, connect with a DSN-less connection string:

Driver={PostgreSQL ODBC Driver (psqlodbc2)};Server=localhost;Port=5432;Database=mydb;UID=postgres;PWD=secret
