We're looking to migrate from MSSQL to Postgres. I'm intending on using sql servers bcp tool for generating csv that we'll import into postgres with the bulk copy features. We are however, having trouble getting the DDL migrated. We've. I've gotten it to work by massaging the DDL generated by MMSQL by hand but We need something automated since we have a moving target (still adding tables, columns etc.) and will need to do this more than once.
We're open to commercial and open source products but have not found anything that does everything we need: Tables, serial columns, indexes (unique, multi column etc), defaults and foreign key constraints.
