Interestingly, Ingres was the first database I ever used - running on Unix (v6 or v7?) on a PDP 11/34. Since then, I've ambled through Oracle, SQL Server, etc, but I'm currently using PostgreSQL on a project, and loving it. The native spatial types are really handy for what I'm implementing, and the speed and stability are great.
