Yes, it's doable, but it's not as straighforward as
   mysqldump -someflags mydbname | psql -someotherflags pgdbname

I suggest you start by checking the resources/articles in the MySQL 
section of http://www.postgresql.org/docs/techdocs.3 (which I'm glad to 
say is much better organized and comprehensive than when I had to do 
it).  FWIW, I converted using CSV as the intermediate format, and the 
dates and timestamps were the trickiest, which required the use of 
"staging" tables (with a textual representation of the columns).  An 
interesting side effect was discovering data inconsistencies in the 
MySQL database since as part of the conversion I implemented foreign key 
constraints under PostgreSQL (which were missing in the former).
