The PostgreSQL Windows installer (pgInstaller) is a Windows Installer based package that will install PostgreSQL as a service on your PC, along with pgAdmin III for management and development tasks. In addition a package manager called StackBuilder is included and will download and install any additional PostgreSQL software or drivers that you require.
Note: Only versions 8.2 of PostgreSQL and above are supported on Windows.
pgInstaller is maintained by Dave Page and Magnus Hagander.
