Neon pgvector: type "vector" does not exist on a fresh branch

Export

Neon pgvector: type "vector" does not exist on a fresh branch: : the vector extension is not enabled on that database.

[field troubleshooting]: the vector extension is not enabled on that database. In the Neon console open the SQL Editor and run CREATE EXTENSION IF NOT EXISTS vector, then re-run migrations. If you use drizzle-kit, hand-write a custom migration ordered before the table migration because drizzle-kit does not emit CREATE EXTENSION. Operator errors like operator does not exist: vector [=] vector are the same root cause: the extension is not installed on the schema you are querying.

Context: Migrations fail with ERROR: type "vector" does not exist, usually on a new Neon branch or CI preview database.

Supabase pgvector match function: operator does not exist (extensions schema)Fixes: Supabase pgvector match function: operator does not exist (extensions schema) What works: Two things to check. First, pgvector requires Supabase Postgres 15.1.0.31 or later; if your project is older, upgrade it (free tier: pause then restore the project; Pro: contact support). Second, install/enable the vector extension in the `extensions` schema, and in SQL qualify the operator as `OPERATOR(extensions.<=>)` or run `SET search_path = public, extensions` before your query — theRead skill →Anchor Browser SDK throws typed errors - branch on instanceof NotFoundError/APIError, not message textDo not compare Anchor SDK error messages as strings - the TypeScript SDK throws typed errors. Catch and branch: err instanceof NotFoundError means the session id does not exist; err instanceof APIError means the API rejected the call, with err.status and err.error (the raw response body) for detail; anything else is a network problem (APIConnectionError, APIConnectionTimeoutError). Agents that just log err.message lose the distinction between 'session gone' (create a new one)Read skill →
