Description
Since some recent releases (likely 64, when PEP-660 was implemented), installing psycopg with -e results in a broken package, where psycopg is an empty namespace.
This is an example of broken run. This is a similar run whose difference is installing psycopg without the -e flag, in order to test a depending package.
