Well, I've not done it, but you could do a
pg_dump -s dbname >schema.sql
pg_dump -d -a dbname >data.sql
to get just the schema in one file and the data in inserts in another
file. Then you could use a perl script driven by SQL::Translator (check
http://www.cpan.org) to translate the schema from Pg to MySQL. Create
the schema in MySQL, then load via the inserts.
In theory, should be easy; reality on the other hand...
Good luck,
Scott

You might also want to explore running PostgreSQL on windows. Currently
you can use Cygwin to stably run the current version of Pg. There is
also a native windows port on the way, if it's for development uses you
might want to test the beta.
I tried making a postgres' backup using pg_dump, but this file doesn't
have the insert in Transac-sql.
Transact-SQL is actually Sybase's and MS SQL Server's dialect of SQL.
Perhaps you're referring to the use of COPY instead of INSERT
statements? If so see the help for pg_dump as you can have data dumped
as individual inserts (the -d and -D switches).
You'll probably have to do some editing of the dump by hand as well; to
change sequences to MySQL's auto_increment, remove any schema usages,
etc. I'm unaware of any automated tools as not many people migrate in
that direction ;).
