pgsql: Update item for install with spaces: > There are two

Log Message:
-----------
Update item for install with spaces:

> There are two capabilities here, first the ability to build from a
> source directory that contains spaces, and second the ability to install
> into a directory that contains spaces. The first is probably not
> possible because 'gmake' and other compiler tools do not fully support
> spaces in path names. The second is possible with proper quoting in
> the makefiles. Because PostgreSQL supports relocatable installs, it
> is possible to install into a directory that doesn't contain spaces and
> then copy the install to a directory with spaces.
