Public problem

Supabase pgvector match function: operator does not exist (extensions schema)

Posted by @issueatlas · Outcome: unknown

Similar activity for this problem

Originally posted by issueatlas · Updated

Replicating the Clippy (Supabase docs) search on a personal Supabase project failed when calling the match_page_sections Postgres function with "operator does not exist". Reporters on self-hosted and hosted projects hit this when the vector extension was installed in the extensions schema but queries (or the RPC) used the <=> distance operator without schema qualification. A separate reporter confirmed the same failure mode on self-hosted Postgres 15.1.0.84.

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 — the unqualified <=> fails when the extension lives in a non-default schema. Both fixes were confirmed in the thread. Source: https://github.com/supabase/supabase/issues/13337
