SettingsBuilder not using the correct installation_dir #235
Description
What steps will reproduce the bug? (please provide code snippet if relevant)
I have a barebones test case (running MacOS 26.3.1 on an M1 Macbook Pro, if that's relevant):
use postgresql_embedded::{PostgreSQL, SettingsBuilder, VersionReq};
#[tokio::main]
async fn main() {
let version_req = VersionReq::parse("=18.3").unwrap();
let settings = SettingsBuilder::new()
.version(version_req)
.trust_installation_dir(true)
.build();
println!("binary_dir: {:?}", settings.binary_dir());
println!("installation_dir: {:?}", settings.installation_dir);
println!("data_dir: {:?}", settings.data_dir);
println!("releases_url: {:?}", settings.releases_url);
println!("socket_dir: {:?}", settings.socket_dir);
let mut db = PostgreSQL::new(settings);
db.setup().await.unwrap();
db.start().await.unwrap();
db.stop().await.unwrap();
}
What happens?
This prints the following output:
binary_dir: "/Users/dacut/.theseus/postgresql/bin"
installation_dir: "/Users/dacut/.theseus/postgresql"
data_dir: "/var/folders/vg/95k36mn14x3_1cxqb8sd9ktw0000gn/T/.tmpRlHeVQ"
releases_url: "https://github.com/theseus-rs/postgresql-binaries"
socket_dir: None
And then crashes:
thread 'main' (20397436) panicked at src/main.rs:16:22:
called `Result::unwrap()` on an `Err` value: DatabaseInitializationError("No such file or directory (os error 2)")
I'll include the full stack trace in a comment in case it's relevant.
What did you expect to happen instead?
This should initialize the database properly
Other observations
The installation_dir appears to be incorrect. On my system, the resulting database is installed to $HOME/.theseus/postgresql/18.3.0.
If I manually force the install_dir in SettingsBuilder to be $HOME/.theseus/postgresql/18.3.0, this works as expected.
