PostgreSQL has had a few bugs over the year that could have resulted in data corruption, but they're pretty rare and fixed as soon as they're found. PostgreSQL is the most reliable software I run, and virtually the only major piece I don't hesitate to upgrade without waiting to see what bugs other people find first. 4) What is the OS of choice for *_serious_* PostgreSQL installations? That's a religious question, not a technical question. I think even Microsoft makes a decent server OS nowadays. But I expect a large majority of PostgreSQL installations are running on Linux, as are the vast majority of all server apps nowadays. Having said that, I don't run a "serious" PostgreSQL installation; some of the people here run databases that do tens of thousands of TPS and hold many TiB of data. You'd have to ask them I guess.
