Postgresql wire protocol proxy for duckdb. In other words, this is a network proxy to allow access to your duckdb files over the postgresql wire protocol.
Duckdb is an embedded database, and in some circumstances you'd want to share/connect to it over network.
Some clients/applications might not have a duckdb option but have a way to connect to a postgres server. (eg: grafana)
As usual you can do
go install github.com/ybrs/pgduckdb@latest
You can run pgduckdb pointing to your duckdb file
