Recommendation for RDBMS for large table I have been asked for recommendation on the optimal RDBMS for a large amount of data. The largest table would contain 2TB of data. My own largest table is only 400GB (mysql, performs very well). 

The individual rows are going to be short, no blobs/etc, just a lookup table. 

Is PostgreSQL nowadays performing better than MySQL? Can I ask DBAs with tables in this order of magnitude for their experience? Oracle might be considered as well. The available hardware is probably a standard linux box with about 64G ram.
The size of the tables really doesn't matter all that much. It's all about how well indexed the tables are and how many people are using the database at once.

In my case I've got clients with billions of rows in a single table where the table size is about 1 TB and another 2 billion row table which has blobs.  These tables crank without performance issues at all.

In this case the server has 1TB of RAM, 80 cores, and is running Microsoft SQL Server 2008 R2.  Granted not all that helpful if you want a *nix OS, but it gives you some ideas that most database platforms can handle just about everything.
