This is what I was looking for! The PostgreSQL persistent memory to the LangGraph. I needed it in TypeScript, but at least it's available in Python. Don't have so much information about it on the Web. Thank you!
@rokbenko I found documentation on the PostgresSaver. Do you think it’s still in beta? Possible to find by searching on the website: 'persistence-postgres'. The direct link doesn't work :(
Hi, thank you for this amazing tutorial, keep doing it :)! I have a couple of questions I hope you can help with. Specifically, do you know how to interact with the database for tasks like removing a thread ID or checkpoint ID? I couldn’t find any direct LangGraph operations with the memory in the documentation for handling these scenarios. My current workaround is using direct PostgreSQL queries, but I’m unsure if that’s the best approach. Would love to hear your thoughts if you’ve worked on something similar. Thanks in advance!
Hey man, thanks for the video. It was really helpful. I am using the same code as you used in your video and I am getting this error: psycopg.errors.DuplicatePreparedStatement: prepared statement "_pg3_1" already exists I used await memory.setup() as this was first time. I tried to run it with commenting it but it is giving me the same error.

Thank you soo much for the video!! It gives us reference on how to instill Long Term memory to LangGraph Applications. Truly useful!!
❤ I was checking exactly same

@RomanH91 I wanted to show a JS example too, but it looks like LangChain hasn't implemented it in the JS SDK yet.
