# pg_regress Smoke Sticky note for contributors and agents: use [SQL Tests](../../../docs/contributor_guide/sql-tests.mdx) for the current SQL test inventory. This directory is only a minimal extension setup smoke for PostgreSQL packaging-style checks. It is not the primary SQL behavior suite. Use `graph/src/pg_tests/` for pgrx SQL behavior tests and `graph/tests/heavy/` for client/server and operational boundaries.
