Runtime SHAREDIR for testing CREATE EXTENSION - Mailing list pgsql-hackers

I'm trying to understand what options I have to test "CREATE EXTENSION"
w/out installing the extension files in their final destination.

Could not find a way to set SHAREDIR from within psql, nor a way
to specify it in initdb call. Am I missing it something ?

PS: please include my address in replies as I have mail delivery   disabled from the list. Thank you.
