The subscription option max_retention_duration accepts an integer value representing a timeout in milliseconds, where zero means unlimited retention (no timeout). Negative values have no useful meaning, but were silently accepted and stored in the subscription catalog. A negative value causes should_stop_conflict_info_retention() to always return true, because TimestampDifferenceExceeds() treats a negative threshold as already exceeded. This stops dead tuple retention immediately rather than honoring the configured timeout. Fix by rejecting negative values for max_retention_duration during CREATE SUBSCRIPTION and ALTER SUBSCRIPTION.
