My requirements were much less than yours. Single-user on large workstation.

I first tried to use Microsoft Access, but it was too buggy and would not let me design a simple database. I then tried postgreSQL (in about 1996, and it did not work right -- then. So I switched to Informix, which was a pain because it did not have an interface to C++, so I had zillions of little interface routines written in C to be called from C++. But it worked with Red Hat Linux 5.0. When Red Hat upgraded that to 5.2, Informix did not work at all, and Informix was unwilling to help. At that point, I switched to IBM's DB2 and it worked fine, though it was like delivering milk with a fire truck. When I switched to Red Hat Enterprise Linux 3, I had trouble getting DB2 to run. IIRC, the problem was that the interface to the raw file systems changed, and I did not want to pay to upgrade DB2. By then I looked at MySQL and postgreSWL again and I picked postgreSQL because MySQL did not handle transactions in a way I felt confident of. As far as I can tell, postgreSQL works fine the way I run it. It seems to be faster, even without raw file systems, than I managed to get DB2 to run with them.
