see that I don't have enough shared memory, and that I should change the
SHMMAX parameter in the kernel.
I'm not really up for recompiling the kernel, since I'm kinda new to
Solaris. Is there any other way to get rid of this error? I hope so :)

Solaris has a dynamic kernel, so you don't have to rebuild.

You can edit the file :

/etc/system
* Oracle shared memory
set shmsys:shminfo_shmmax=4294967295
set shmsys:shminfo_shmmin=1
set shmsys:shminfo_shmmni=100
set shmsys:shminfo_shmseg=10
set semsys:seminfo_semmni=100
set semsys:seminfo_semmsl=100
set semsys:seminfo_semmns=250
set semsys:seminfo_semopm=100
set semsys:seminfo_semvmx=32767

these are some parameters from a solaris machine on which we run Oracle.

TIP 2: you can get off all lists at once with the unregister command
(send "unregister YourEmailAddressHere" to majordomo@postgresql.org)

You can also bring down the number of allowed simultanous connection using
for instance -N 16 -B 32 at the commandline of the postmaster.

I have experienced the same thing on our Sun, this worked fine and is no
problem if you don't need that much connections.
