paradedb/paradedb#1473 seems similar

[stuta]

This worked:

export SDKROOT=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk

cargo pgrx install --release

• this failed because it could not write to Application folder
• sudo cargo pgrx install --release failed also

cargo pgrx install --sudo --release

• this wrote files to pgvectorscale-0.5.1/target/release/vectorscale-pg17/Applications/Postgres.app/Contents/Versions/17/ and I was able to copy files to application.

After Postgres.app restart CREATE EXTENSION IF NOT EXISTS vectorscale CASCADE; worked.

Maybe readme needs some tweaking.
