Re: Ingres dump files to PostgreSQL

Kaare,

I have a utility which will read Ingres r3 data files directly but I 
don't think it would be that reliable to use.  I suggest you get one of 
the open source database conversion utilities written in Java, they work 
pretty well.  You can find a few of them on SourceForge/Freshmeat.

Thanks!
