I've done some installs of PostgreSQL 9.0 64 bit on Windows Server 2008 R2 Standard.
When I connect to these instances, PGAdmin complains of the following:
The server lacks instrumentation Functions.
Apparently one is supposed to use the "official" pgInstaller program to install contrib modules in Windows PostgreSQL installs, including the server instrumentation.
However, the pgInstaller is only being maintained up to the PG9.0 RC, not the latest 9.0.1 version.
Given that, how do I get non-default contrib modules installed?
