Why are there 2 libpq folders in PostgreSQL

Question

In the PostgreSQL source code there are 2 libpq folders :

src/interfaces/libpq
src/backend/libpq

What is the difference between them?

As from what I have seen only the one present in interfaces folder is compiled and referred.

One's for backend (for the server to receive connections -- src/backend/libpq) and one's for frontend (for clients to make connections to the server -- src/interfaces/libpq)

Disclosure: I work for EnterpriseDB (EDB)

src/interfaces/libpq contains the code for the libpq client shared library.

src/backend/libpq contains the server-side implementation of the frontend/backend protocol.
