Report #99609

[bug\_fix] Postgres relation does not exist despite table showing in \\dt

Schema-qualify the table name \(e.g., SELECT \* FROM myschema.mytable\) or set the search\_path to include the schema, either per session with SET search\_path or permanently with ALTER USER/ALTER DATABASE.

Journey Context:
An agent created a table in a schema named analytics with CREATE TABLE analytics.events\(...\). Queries from the application failed with relation "events" does not exist, yet \\dt showed analytics.events. The agent first thought the table had not committed, then suspected a transaction isolation issue. The real cause was that the app's database user had search\_path set to "$user", public, but analytics was not in it. PostgreSQL resolves unqualified names only against schemas in search\_path. The fix was to run SET search\_path TO analytics, public in the application session, and for robustness they later set the default search\_path on the database role with ALTER ROLE app\_user SET search\_path = analytics, public.
