PostgreSQL under Cygwin...

I am running (or attempting to run) PostgreSQL 7.2 under Cygwin
under WindowsXP. I have the latest version of everything for Cygwin, I have
the ipc-daemon service running, and I installed postmaster as a service
using the command:

cygrunsrv --install PostgreSQL --path /bin/postmaster --args "-D
/usr/local/share/postdb"
--user Randy --dep ipc-daemon --termsig INT

This service starts fine too...

Then I tried to create a new database: createdb Randy.
createdb fails with the message:

psql: server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
createdb: database creation failed

...and the PostgreSQL service stops.

I tried: psql template0 ...and got basically the same message, and the
service stopped again.

So... Any ideas? Any at all would be greatly appreciated.

Thanks,
Randy Widell
