I can reproduce the above. From the following stackdump (from psql):
$ cat psql.exe.stackdump
Exception: STATUS_ACCESS_VIOLATION at eip=6108D4A4
eax=0A010462 ebx=0A010462 ecx=0000006D edx=00000000 esi=0022FC98 edi=0A010462

..
we can conclude that the crash is inside of the Cygwin DLL. Why?
Because the Cygwin DLL is based at 0x61000000. At first glance, it
appears that the 7.2 psql is tickling a Cygwin bug. BTW, if I connect
to a 7.2 backend from a 7.1.3 psql, then all appears to be OK.
I will build a debuggable DLL from the latest Cygwin CVS and continue
debugging. I will report back when I have more info (unless someone
else beats me to it).
