well, the "load" and the on-demand (from inside a query) dynamic 
loading code call exactly the same routines to do the dirty work.

"ld -A" incremental linking uses an amount of /tmp space at least
as large as your postgres binary.  that's one reason why it was
jettisoned in favor of the dlopen(3) interface (which we were 
finally able to do after andrew yu wrote a very slick and very
fast dynamic loading package for ultrix..).
