Yes, it should be accessible to shared libs that are loaded into a
backend.

If I'm visualizing your setup correctly, you are trying to load this
code into a Perl executable?  It's not going to work to load backend
code into Perl, because none of the backend support routines are going
to be accessible.  Probably CurrentMemoryContext is just by chance the
first unresolvable symbol the linker found --- there'll be more if you
get past that one.

Code that's supposed to go into non-backend contexts shouldn't be using
any Postgres-specific include files...
