These schemas are aliases for *schemas*. Only PostgresConnection has
more than one aliases. And there is no 'pygresql' schema - it was removed
in 0.12.

The 'backend' parameter selects a *DB API driver*. I.e., you can select
psycopg2, psycopg1 or pygresql driver regardless of the schema.

A Connection class knows it's name via cls.dbName. All Connection
classes except for PostgresConnection have one alias that is exactly the
same as dbName. PostgresConnection has 2 aliases, but dbName is 'postgres'.
If you want to change the schema probably it's best to create a new
Connection class. Inherit it from PostgresConnection and redefine its
dbName.

DSN strings is a rather old concept. I maintain it just in case, but I
use dsn_dict and I think it's te preferred way.

No idea. I develop on Linux.

License. SQLObject is LGPL-licensed. A code you want to add to SQLObject
itself must be LGPL-licensed. External code (DB API drivers not included
into the SQLObject code base) doesn't matter.
PS. Happy New Year to all!
