I see. Envrc looks superior. Good to know.
You've covered all my bases. Shooting in the dark, I would confirm/check the
following:
How do you know that envrc is working otherwise?
When you switch to a direnv controlled buffer do you get any informative
diagnostics in *Messages*?
Do you get any more if you first `(setq envrc-debug t)`?
Is this buffer in the same directory as the .direnvrc file?
Presumably TRAMP is not in the mix in any way.
Variable sql-postgres-program is unchanged from default value of psql
What is result of
m-x shell-command
which psql
and does it change as expected/required depending on the current active
.direnvrc?
What happens if you eval (getenv 'psql) while in buffer governed by direnv, or
alternatively
m-x getenv
psql
If you `m-x shell`, does normal direnv work as expected in the created shell?

Gotta get guix rolling again. Hope to do this RSN.
