Bien, el dato exacto no lo hallo. Pero esto puede servir (espero).

6.  PostgreSQL Supports Extremely Large Databases greater than 200 Gig

Performance of 32-bit cpu machines will rapidly decline when the
database size exceed 5 gig. You can run 30 gig database on 32-bit cpu
but it will not be very effective. There is limitation imposed on the
amount of RAM (maximum of 2 gig only), limitation on the file system
sizes and also on the operating system.  The operating system on
32-bit cpu will be "bumping it's head" too many times on the "32-bit
ceiling".

If you need to use extremely large databases (greater than 5
gigabytes), it is strongly advised that you use 64-bit machines like
Digital Alpha cpu, Sun Ultra-sparc 64-bit cpu, Silicon graphics 64-bit
cpu, upcoming Intel Merced IA-64 cpu, HPUX 64bit machines, IBM 64-bit
machines. Compile PostgreSQL under 64-bit cpu and it can support huge
databases and large queries. Performance of PostgreSQL for queries on
large tables and databases will be several times faster than
PostgreSQL on 32-bit cpu machines. Advantage of 64-bit machines are
that you get very large memory addressing space and the operating
system can support very large file-systems, provide better performance
with large databases, support much larger memory(RAM), have more
capabilities etc..
