The server lacks instrumentation functions, PgAdmin 1.4 beta2

["Jean-Pierre Pelletier" <pelletier_32(at)sympatico(dot)ca>]

Hi,

PGAdmin display "The server lacks instrumentation functions"
when opening server status.
I got rid of that message by manually executing admin81.sql in database 
"postgres".

Is this the intended behavior?

I am on Windows XP Service Pack 2.
I've installed PostgreSQL 8.1 beta3 with the Windows installer
which installed pgAdmin 1.4 beta2.
I didn't run initdb manually, the cluster was initialized by the Windows 
installer.

Thanks,
