Enable the feature:
cargo add pglite-rs --features multiple-processOpen:
use pglite::{MultiProcessOptions, PGlite};
let db = PGlite::open_multi_process("./data", MultiProcessOptions::default()).await?;
Multi-process mode extracts the bundled runtime, initializes the
data directory, starts bin/postgres with
listen_addresses= and a private Unix socket, then
creates a connection pool behind the same PGlite API.

socket is enabled.
