Since pgAdmin4 2.0 is targetting v10 of PostgreSQL, I thought it would support scram authentication in addition to md5. In fact, I thought this would happen automatically simply by virtue of using the latest libpq.dll, without any coding changes to pgAdmin4 itself.
But when I set myself a scram-hashed password (using psql) and then try to connect with pgAdmin4, I get the message "authentication method 10 not supported", which is the message you get from pre-v10 versions of libpq.
Is this a known issue? Does the installer include the wrong libpq.dll?
pgAdmin4 uses psycopg2 in order to communicate with Postgres and psycopg2 is lacking support for Scram at a moment, and I think developers are already working on adding support for PG10 (https://github.com/psycopg/psycopg2/pull/576).
