Relevant system information:

• OS: macOS 14.2.1 (23C71)
• PostgreSQL version (output of SELECT version();): [e.g. 12.0, 13.2, etc]
• TimescaleDB Toolkit version: "PostgreSQL 16.1 on aarch64-apple-darwin21.6.0, compiled by Apple clang version 14.0.0 (clang-1400.0.29.102), 64-bit"
• Installation method: source— following "Building and Installing the extension"

Describe the bug
Followed source install
.

To Reproduce
Did the following:
git clone https://github.com/timescale/timescaledb-toolkit.git
cd timescaledb-toolkit
OK and folder is there.
Added export PGRX_HOME="${HOME}/.cargo/“ to .zshrc after next step failed
cargo pgrx install --release # reran successfully

Then the following

timescaledb-toolkit/extension on  main is 📦 vtimescaledb_toolkit@1.18.0-dev via 𝗥 v1.74.0

note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

The other files in /Applications/Postgres.app/Contents/Versions/16/lib/postgresql/ are .dylib and no .so files.

This is the first pg extention I've installed with Rust. I am a little surprised that the install is into the Postgres.app rather than /Users/gscar/Library/Application Support/Postgres/var-16/

Thanks for any suggestions on how to proceed.

Did you find a solution to this?

@adam-micromelon I encountered this a couple of days ago. I was able to get it working by replacing any instances of .so with .dylib in tools/post-install/src/main.rs and re-running the release command.
