After my second post I spent another night fiddling with this stuff
and I arrived basically at the same conclusion. Running ipctest h from
different accounts *will* result in a misleading error message unless
you remove previously created files in /tmp. E.g. I first ran ipctest
h as user postgres (the account cygipc runs with) without problems,
then as a regular user. The second time it failed. Removing the stuff
in /tmp makes it work again. I attribute this to my complete ignorance
how ipctest works.

Removing the stuff in /tmp coincidentally cured the postgres problem
as well as you already had found out. I still cannot connect as a
regular user but this appears to be a postgres permission problem, no
shared memory problem (so this will appear in a separate thread on
this mailing list unless I can figure it out tonight...).

Thanks Fred and Chuck for your input
Markus
