FATAL: shmat(id=1179648) failed: Invalid argument

Hi,

creating template1 database in /var/pgsql/data1/base/1... DEBUG:
invoking IpcMemoryCreate(size=1081344)
FATAL:  shmat(id=1179648) failed: Invalid argument

What's the problem why is shmat passed a wrong id?

I temporarily need Postgres running on Windows98
just to write a client app and I'm stuck at this point.
The same problem has been posted on the cygwin list
but there's no solution so far.
I've got a recent cygwin and tried cygwin postgres 7.4.2-1 and 7.4.3-1
Do I need to tweak the configuration file for cygserver?
I guess the problem is on the cygwin's side
but got no clue how to tackle it.

Help greatly appreciated.

Greg
