Start with the linked TeamCity build and its artifacts, then inspect pkg/sql/tests/rsg_test.go around lines 113 and 593 for how TestRandomSyntaxSchemaChangeColumn reports failures. Reproduce the failure using the recorded release commit and test logs, identify the underlying cause, and consider the issue done when the test passes without leaving test logs behind.
