I'm looking to convert a lot of data from Sybase to Postgres. As this will be a painful process, I was wondering if there are any utilities and programs to ease the conversion process. Specifically, I'm looking for help in 3 areas.
1. Recreation of the schema, especially converting triggers, data types, and functions. 2. Converting SQL scripts and cron jobs where there are incompatibilities (e.g. sybase : isnull(...) :: postgres : coalesce(...) ). 3. There is an ancient GUI that we use to interface to sybase (it's based on APT, I believe). The nice thing is it can run external commands, and interfaces somewhat nicely with Kerberos. Is there any piece of middleware (preferably GUI-based, though web-based may do) for postgres that can do this?
Of course I can spend hours tracking down cron jobs, apps, and scripts, painstakingly recreating triggers and functions, and write my own GTK-based GUI, but if there's anything that can help me, please let me know.
