What size barrier?  MySQL's size limit was Linux kernel limitation in the 
size of a file (2 GB).  PostgreSQL suffered from the same limitation.  
That restriction went away with the 2.4 kernel.  The limit is 2^32 blocks.  
If you're using 2K or 4K blocks, that's a pretty big file 
(4096 X 2^32 = 17,592,186,044,416) or 17 Terabytes.  
MySQL's limit is smaller than that.  In fact, according to the folks at 
MySQL, it scales to very large files better than Oracle does. MySQL has 
made major changes when going to 4.0.  In fact, if  you install it, you 
need to recomile anything that uses shared libraries to access it.

However, MySQL makes their benchmarking software availabel on their 
website and you can do your own comparison.
