PostgreSQL installation failed--the database cluster initialisatio

PostgreSQL can never accept more than about 125 connections at the same time, my hardware is very powerful!

This happens because some PostgreSQL says that dependent libraries depend on user32.dll, and user32.dll to allocate memory from the Desktop Heap. The desktop heap allocates memory for each login session, allocating approximately 512KB per non-interactive session, while each Postgres.exe process consumes about 3.2KB of the "desktop heap", so that approximately 125 connections can run out of all " Desktop Heap "space.   However, this does not happen when running from the command line, because the command line is an interactive logon session, and usually requires only a 3MB size "Desktop Heap". http://support.microsoft.com/kb/184802

To solve this problem, you must increase the size of the noninteractive "Desktop Heap" by modifying the SharedSection value in the registry, as described in the Microsoft Knowledge Base article. It is important to note that setting too high a value can cause the system to fail to start.
