Maybe check the swap usage with 'swap -l' which reports reliably if any
(device or file) swap is actually used.

I think Solaris 'top' does some strange accounting to calculate the
'swap in use' value (like including used memory).

It looks to me like you are using no (device or file) swap at all, and
have 1.3G of real memory free, so could in fact give Postgres more of it :-)
