I gave some training a few years ago for devs that were migrating from
SQLServer to PostgreSQL and they had a bunch of SP, some of easy
resolution, and others that where impossible with PG functions written
in plpgsql. They used CURSORS a lot to simulate what they did with
SQLServer (there was a better solution, but time was crucial, and they
decided for that approach)
