Hi Joe,
the general rule on Solaris SPARC is:
- if you need to address a big size of memory (over 4G): compile in 64bit
- otherwise: compile in 32bit ;-)
It's true that 32bit code will run faster comparing to 64bit ont the
64bit SPARC - you'll operate with 2 times shorter addresses, and in
so

Most non-gcc compilers disable optimization altogether if you enable
debug :-(.
With a 16 CPU, 32 GB Solaris Sparc server, is there any conceivable
reason to use a 32 bit build rather than a 64 bit build? Apparently the
Sun PostgreSQL package includes a README that indicates you might want
to think twice about using 64 bit because it is slower -- this seems
like outdated advic
