vec2pg is a CLI utility that facilitates the migration of data from various vector databases into Postgres with associated ids and metadata. The tool supports migrating from Pinecone and Qdrant, and it allows users to manipulate the data using SQL to transform it into their preferred schema. When migrating, users should increase their Supabase project's disk size to accommodate the vectors. The performance of `vec2pg` is dependent on several factors, including network speed, vector dimensionality, and metadata size. Pinecone and Qdrant collections can be migrated at rates of 700-1100 records per second and 900-2500 records per second, respectively. Postgres/pgvector offers several benefits, including performance, scalability, security, backups, row-level security, and compatibility with a wide ecosystem of tools. The tool is designed to make it easy for users to efficiently copy their data from various vector databases into Postgres, allowing them to manipulate the data using SQL and transform it into their preferred schema.
