Thread: Memory problems on Windows XP
I have recently installed Cygwin PostgreSQL using Windows XP. I have an 80 gb hard drive and 512 mb of RAM
I was able to successfully use Initdb, and seem to be able to start Postmaster, but when I try to use Createdb I keep getting the following message on the Server side:
bash-2.05b$ postmaster -D data -i

This error usually means that PostgreSQL's request for a shared memory segment exceeded available memory or swap space. To reduce the request size (currently 1441792 bytes), reduce
PostgreSQL's shared_buffers parameter (currently 64) and/or its max_connections parameter (currently 32).

The PostgreSQL Administrator's Guide contains more information about shared memory configuration.
and
bash-2.05b$ createdb -h localhost testdb
psql: server closed the connection unexpectedly
This probably means the server terminated abnormally before or while processing the request.
createdb: database creation failed

createdb: database creation failed
on the client side.
I'm installed the following versions:
Cygwin 1.3.12-4
Postgresql 7.2.2-1.
I can't figure out how to resolve this.

Did you recently switch the user that postmaster runs under? If so,
then try the following:
$ rm /tmp/cygipc* /tmp/MultiFile*
Otherwise, try the following:

I'm glad that Cygwin PostgreSQL is working for you now. However, I don't understand how reinstalling should have solved your problem. Jason
