Hey there;
As Tom notes before maybe you're not using the right postgres. Solaris 10 comes with a postgres, but on SPARC it's 32 bit compiled (I can't speak to x86 Solaris though).
Assuming that's not the problem, you can be 100% sure if your Postgres binary is actually 64 bit by using the file command on the 'postgres' executable. A sample from 64 bit SPARC looks like this:
postgres: ELF 64-bit MSB executable SPARCV9 Version 1, UltraSPARC3 Extensions Required, dynamically linked, not stripped
But x86 should show something similar. I have run Postgres up to about 8 gigs of RAM on Solaris without trouble. Anyway, sorry if this is obvious / not helpful but good luck :)

Either it's not really a 64-bit build, or you made an error in your
math. What did you try to set shared_buffers to, exactly? Did you
increase any other parameters at the same time?
