There is NO MAX....

It is according to your hardware you have, and the db you have.   

Not entirely true.  on 32 bit OS / software, the limit is just under 2
Gig.  I'd imagine that the limit on 64 bit hardware / software is
therefore something around 2^63-somesmallnumber which is, for all
practical purposes, unlimited.
 

Its limited only by the hardware and OS you are running.    Some OS's on 32bit allow for up to 4 gigs but you have to leave room for the OS and other running processes.  On 64 bit hardware it can be limited by the Hardware along with OS where its artificially limited to 32gigs, 64 gigs and 2TB  seem to be the most common limits set by the hardware or OS.   But again you have to leave room in these setting for other processes if not out memory errors will occur and may crash the server.

In general these setting are only limited by the Hardware and OS
