These were the places I read when I had to migrate some MS SQL DB to
Postgresql.

I admit I mostly did it by exporting csv from MS SQL[1],
refactoring the schema and rewriting from scratch functions... but
those were the places where I read the info I needed.

[1] suddenly MS SQL became unable to export proper csv so I remember
I wrote an rudimentary odbc2csv tool as well. Since it was inspired
by an even more rudimentary work of a colleague I'll ask if he can
release it under GPL if you'll find yourself in the need of such a
beast.
