Check Existing Issues

  • I have searched the existing issues and discussions.
  • I am using the latest version of Open WebUI.

Installation Method

Git Clone

Open WebUI Version

0.6.9

Ollama Version (if applicable)

No response

Operating System

Linux (Azure WebApp)

Browser (if applicable)

No response

Confirmation

  • I have read and followed all instructions in README.md.
  • I am using the latest version of both Open WebUI and Ollama.
  • I have included the browser console logs.
  • I have included the Docker container logs.
  • I have listed steps to reproduce the bug in detail.

Expected Behavior

When using an Azure PGSQL database (PG v16.8, PGvector v0.8.0), the vector database is initiated properly when first booting the app.

Actual Behavior

The database init fails, and the app crashes. When removing the VECTOR_DB=pgvector variable (fallback to local chroma), the app starts properly.

The EOF issue also happens when calling the init queries from CLI.

Steps to Reproduce

Set the following env vars:
VECTOR_DB=pgvector
PGVECTOR_DATABASE_URL= posgtresql://xxxxxxx

Start the openwebui container, and wait for it to crash.

Additional Information

Hello;

First of all, thank you for this great project.

A bit of context: we are running PGVector on an Azure PaaS database with PGSQL 16.8 and PGVector 0.8.0.
The vector database fails to init, and the openwebui container crashes because of this.

Side note if that matters, we have another instance of OpenWebUI running on PGVector 0.7.0, without any issue, but we are not sure if v0.8.0 is the issue.

Originally created by @valentin-pringault on GitHub (May 14, 2025). Original GitHub issue: https://github.com/open-webui/open-webui/issues/13885 ### Check Existing Issues - [x] I have searched the existing issues and discussions. - [x] I am using the latest version of Open WebUI. ### Installation Method Git Clone ### Open WebUI Version 0.6.9 ### Ollama Version (if applicable) _No response_ ### Operating System Linux (Azure WebApp) ### Browser (if applicable) _No response_ ### Confirmation - [x] I have read and followed all instructions in `README.md`. - [x] I am using the latest version of **both** Open WebUI and Ollama. - [x] I have included the browser console logs. - [x] I have included the Docker container logs. - [x] I have listed steps to reproduce the bug in detail. ### Expected Behavior When using an Azure PGSQL database (PG v16.8, PGvector v0.8.0), the vector database is initiated properly when first booting the app. ### Actual Behavior The database init fails, and the app crashes. When removing the VECTOR_DB=pgvector variable (fallback to local chroma), the app starts properly. The EOF issue also happens when calling the init queries from CLI. ### Steps to Reproduce Set the following env vars: VECTOR_DB=pgvector PGVECTOR_DATABASE_URL= posgtresql://xxxxxxx Start the openwebui container, and wait for it to crash. ### Logs & Screenshots Docker logs : ERROR [open_webui.retrieval.vector.dbs.pgvector] Error during initialization: (psycopg2.OperationalError) SSL SYSCALL error:

### Additional Information Hello; First of all, thank you for this great project. A bit of context: we are running PGVector on an Azure PaaS database with PGSQL 16.8 and PGVector 0.8.0. The vector database fails to init, and the openwebui container crashes because of this. Side note if that matters, we have another instance of OpenWebUI running on PGVector 0.7.0, without any issue, but we are not sure if v0.8.0 is the issue.
