That fixes the segfault, thank you.

It worked with

extension_control_path = '/Users/david/Downloads/share/postgresql/extension:$system’

But not with

extension_control_path = '/Users/david/Downloads/share/postgresql:$system’

And here is where the control file actually is:

❯ ll ~/Downloads/share/postgresql/extension  total 8
-rw-r--r--  1 david  staff   161B Apr 24 18:07 semver.control

So I don’t know the answer to your question, but it’d be handy to have functions that return a list of resolved paths
fromextension_control_path and dynamic_library_path, since they get mangled. 

Best,

David
