I'm unable to run initdb manually: C:\Program Files\PostgreSQL\8.2beta1\bin>initdb -D test The program "postgres" is needed by initdb but was not found in the same directory as "C:\Program Files\PostgreSQL\8.2beta1\bin/initdb". Check your installation. > Also, does it work if you pick a different locale/encoding? (it really > shouldn't make this kind of error, but worth checking) Please re-confirm if you want that I try this. I think it may be the same shared memory allocation issue which I descibed in message from April 5, 2006. Computer has 8 GB RAM. If you tell me how to run initdb manually I can try it.
