When setting the 
MELTANO_DATABASE_URI
env var to be a postgres db (such 
<postgresql+psycopg://user:password@localhost:5432/meltano>
) and running 
meltano state list
I get the following error 
No module named 'psycopg'
I have tried • Adding the postgres utility to meltano - 
meltano add utility postgres
• Adding python packages 
postgres
, 
psycopg2
, 
psycopg2-binary
• Re-reading over and over the docs here and here to no avail I am at a dead end 😞 Help?

I would try changing your URL to start with 
postgresql+psycopg2://
.

@Chase Brammer how did you install meltano? You might need to install it as 
meltano[postgres]
and we could probably make it more explicit in that doc.

@Edgar Ramírez (Arch.dev) install with uv @BuzzCutNorman changed, no joy 😞
Side note, in testing the tap-github plugin I targeted the MeltanoLabs org to sync.. and @Edgar Ramírez (Arch.dev) has a crazy amount of commits/activity

> install with uv Ok, so if you did 
uv tool install meltano
you might wanna do 
uv tool install --from meltano[postgres] meltano
crazy amount of commits/activity
🙈

🤔 Will try to debug more, but • 
uv tool install --from meltano\[postgres\] meltano
(needed to add the \ to install • Same error while running both 
uvx meltano state list
and 
uv tool run meltano state list
TL;DR: that didn't work 😞 I thought it was maybe a lingering version of meltano being called by uvx. Purged my entire system of all meltano items, and installed again with [postgres] and verified the tool installed by looking at the 
~/.local/share/uv/tools/meltano/uv-receipt.toml
file which has the postgres flag on
Copy code
[tool]
requirements = [{ name = "meltano", extras = ["postgres"] }]
entrypoints = [
    { name = "meltano", install-path = "/Users/myuser/.local/bin/meltano" },
]
e
where meltano
might reveal something

Hold the phone! Just changed back from the suggestion above on the URI 
postgresql+psycopg2
to 
postgresql+psycopg
and we are back in business!
I would have never figured out to install with 
[postgres]
