No, I really mean a library dependency failure.  For example, imagine
that Postgres is compiled on Windows dynamically, and that it depends on
libxml2.dll, which is itself compiled dynamically.  Then imagine, in a
custom build echosystem, that a folk comes in and adds lz support to
libxml2 on Windows.  If Postgres still consumes libxml2 but does not add
in its PATH a version of lz, then a backend in need of libxml2 would
fail to load, causing Postgres to not start properly.  True, painful,
story.
