I have news:
It fails for python too. Using the same files as before and this block:
#+begin_src python
import pandas as pd
import matplotlib.pyplot as plt
#+end_src
It finds matplotlib, but fails to find pandas. I tried the same trick as before
(but with the python executable, no psql), added the line
(org-babel-python-command . ".direnv/.guix-profile/bin/python3")
but is not working.
But if I am in shell, or in a python buffer or in a inferior-python process
Emacs is finding all the libraries and executables.
So, I am assumming that the problem lies in how org-babel searchs the path ...

Is empty when I am not in a direnv controlled directory, the correct path when
I enter to those directories.
