Well, most of our database servers wind up with multiple builds of
PostgreSQL, and we find it is less error-prone for the non-programmer
DBAs to expand a tarball under such a directory from the normal build
(for the appropriate version) and make it there.  There also seemed
some possibility that clearxlogtail would be accepted into the
distribution as a contrib module, so I was trying to have it ready to
go, should that happen.
As an aside, our function for extracting text from a PDF in a bytea
didn't work right when I tried to build it using the PGXS the other
day.  I moved the directory into our PostgreSQL build location and
built it the other way and it worked.  I haven't tracked down why, but
it leaves me leery of carving out the form which worked for me.  (When
you don't really understand something, you resort to superstitious
ritual....)
