I'm kind of inclined not to, because most other ways that you can
specify a database name for a connection also don't downcase.

$ psql Postgres
psql: error: connection to server on socket "/tmp/.s.PGSQL.5440" failed: FATAL:  database "Postgres" does not exist

$ psql postgres
...
postgres=# \c "dbname=Postgres"
connection to server on socket "/tmp/.s.PGSQL.5440" failed: FATAL:  database "Postgres" does not exist
Previous connection kept

This largely stems from an ancient decision that we shouldn't
auto-downcase names coming from a program's command line.
The interaction of SQL and shell quoting conventions is messy
enough that specifying a non-lower-case database, user, etc name
would be pretty annoying if we did do that.
