I may have missed something, but a quick scan of the Mantis code didn't reveal any use of triggers, rules, foreign-keys, user-defined types, etc. Whenever I see that a project has been "ported" to PostgreSQL I can usually be sure that it is not a project that was designed to take advantage of the features and capabilities that PG offers. But I suspect that porting something that uses all the features of mySql to PostgreSQL will be far easier than porting something that uses all the features of PostgreSQL over to mySql (if it is possible at all).
