That's somewhat limiting though, you need to export in the subset of SQL (DDL and queries) compatible to all databases and it is very small indeed (I hope you don't have any textual content of more than 8000 bytes encoded).
But if what you want is to load the data into sqlite, chances are you can just export the sqlite content and load it into Postgres directly, since Richard Hipp (and the SQLite team) more or less consider Postgres to be the reference implementation of SQL: https://twitter.com/dchest/status/469597738431434752
