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.
