Do not treat an active PostgreSQL index build as interrupted.
When two instances start together, the second can observe the first instance’s in-progress index as indisvalid=false and attempt to drop it. PostgreSQL records concurrent builds as invalid until completion, and a concurrent drop waits for conflicting operations. The second instance can therefore remove the completed replacement and start another expensive build. If the legacy index has already been retired and that rebuild fails, last-used lookups lack the intended index. Coordinate migration ownership across instances before checking and dropping an invalid index. (postgresql.org)

Fixed in 7de388e. Before treating an invalid index as interrupted, startup checks pg_stat_progress_create_index and leaves an index another instance is still building to that instance. The old index is dropped only once the new one is valid, so the instance that finishes the build retires it. TestEnsureAuthKeyIndexLeavesAnotherInstancesBuild holds a real concurrent build in progress and checks that a second startup neither drops nor blocks on it; without the guard the test hangs. The SQL-injection note doesn't apply here, because the concatenated names are package constants.

@SantiagoDePolonia, the test verifies that a second startup leaves a build alone while pg_stat_progress_create_index reports it as active. That addresses the tested case. The SQL-injection note does not apply because the concatenated index names are package constants.
The check and drop are still separate operations. If the first build finishes after the second startup reads indisvalid=false but before it checks build progress, the second startup can drop the now-valid replacement index and rebuild it. The test does not cover that interval. Please coordinate the validity check and migration across instances before dropping the index. I’ll keep this finding open.

Learning: In `internal/auditlog/auth_key_index.go`, the SQL DDL statements concatenate the package constants `authKeyTimestampIndex` and `legacyAuthKeySQLIndex`. Those index names are not untrusted input, so this concatenation is not an SQL-injection issue.

The endpoint-label admission registry is mutable package-global state, including its lock and retained labels. This violates the repository directive to avoid hidden global state; encapsulate it in an explicit metrics-label component or hook-owned dependency so its lifecycle and reset behavior are visible and testable. This repository requirement must be satisfied before merging.
