Which is another point I was about to ask. How do these people, running those huge and horribly important databases, ever test a single application change? Or any schema changes for that matter. Do they really type "psql -c 'alter table ...' proddb" and believe they are professional users because they know what they are doing?

I do alter table, but of course before to do it, I run my regression test on a database with almost no data inside. Each stored procedure is tested in order to execute each execution path. In 3 years working in this way I had no a singol failure after an alter schema operation.
