Ah - I misread the docs. Specifically I read this:
"For many extensions this means superuser privileges are needed.
However, if the extension is marked trusted in its control file, then it
can be installed by any user who has CREATE privilege on the current
database"
The rest of that paragraph:
"In this case the extension object itself will be owned by the calling
user, but the contained objects will be owned by the bootstrap superuser
(unless the extension's script explicitly assigns them to the calling
user). This configuration gives the calling user the right to drop the
extension, but not to modify individual objects within it."
To mean that you could mark any extension as trusted in the control file
to allow non-superuser installation.
Thanks,
Brad
