Starting with 2026.01.27-4-rc1 release, Aviator requires the pgvector PostgreSQL extension for the context management feature in Runbooks. This extension must be installed and enabled before upgrading the Aviator application regardless of whether you use Runbooks.

Step 1: Enable the Extension

In cases of cloud provider managed database, the extension should also be preinstalled, you just need to enable it. You can connect to your Aviator database using a superuser account and run:

CREATE EXTENSION IF NOT EXISTS vector;

To verify the installation:

SELECT extversion FROM pg_extension WHERE extname = 'vector';

Cloud provider specific instructions

• Using Amazon RDS / Aurora
• Using Google Cloud SQL
• Using Azure database for PostgreSQL

Self-hosted postgreSQL

For self-hosted PostgreSQL installations, you need to install pgvector manually.

• Option 1: Package manager (recommended)
• Option 2: Build from source

Step 2: Upgrade Aviator

After enabling the pgvector extension, proceed with the standard app upgrade.

The database migration will automatically create the required tables and indexes.

Troubleshooting

"extension 'vector' is not available"

The pgvector extension is not installed on your PostgreSQL server. Follow the installation steps for your platform above.
