Quite apart from any considerations covered by other people, these

not exact equivalents of the MySQL commands, AIUI.
The \copy could definitely be considered a stretch; I know \c supports
more options than the equivalent USE, but isn't it a proper superset
of functionality?
Not really. "use" sets the default db in MySQL (and other DBs like
Sybase and MSSQL). But you don't really connect to a particular
database, unlike Postgres - you connect to the server. And you can
directly query other databases than the default, again unlike Postgres
where you can only directly query the database you're connected to. In
fact, "use" is part of MySQL's SQL dialect, and can be used from any
client, not just part of the metacommands of their commandline client.
See <http://dev.mysql.com/doc/refman/5.5/en/use.html>
