Our builds (those done by the pgAdmin devs themselves, i.e. Windows, macOS, Docker, Python wheel) will all pull the latest version of psycopg in their build process. Psycopg2 2.8.4 was released on October 20th, so pgAdmin 4.15 should have it, but 4.14 will not.
Perfect. This is what we are seeing now. People upgrading to 4.15 are no longer experiencing the issue, whereas they still were with 4.14. Thank you for the work!!!!
