Yes.  By now, if any dump was ever written to your swap partition, it
will most probably have been overwritten by your heavy postgres
activity. :)

In RELENG_6, the dump device is chosen automagically during boot by
/etc/rc.d/dumpon, but this is (alas) not the case in RELENG_5_x, so
you'll have to manually specify it in /etc/rc.conf, i.e:

  dumpdev=/dev/ad0s1b

Then make sure you have enough space in /var/crash, and try to
reproduce your panic...

Also, I think I read somewhere that there used to be problems with
dumping and 3Ware RAID cards (you seem to be using one according to
your kernel config, but you apparently didn't post a dmesg).  However,
it looks like revision 1.22.2.1 of src/sys/dev/twe/twe.c fixed that:

http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/twe/twe.c?rev=1.22.2.1&content-type=text/x-cvsweb-markup

Just to be sure, can you check if you got this version of twe.c, or
1.22.2.2 (which seems to be the RELENG_5_4 version, and thus it should
be fixed).
