Simple tests that only need a PostgreSQL connection to run. These are run by the regress/test_pg_regress.py test, which uses the PostgreSQL pg_regress utility.

To add a new SQL test:

• add sql script to run to neon_regress/sql/testname.sql
• add expected output to neon_regress/expected/testname.out
• add testname to parallel_schedule

That's it. For more complex tests see PostgreSQL regression tests in src/test/regress. These work basically the same.
