The failure is caused by orphaned database records in the vcIntegrity database. Specifically, the pm_recommendation_spec table contains stale entries that lack corresponding parent records in pm_recommendation_info.
vCenter 9.1.0.0 introduces a strict foreign key constraint (FK_PM_RECOMMENDATION_SPEC) to harden database integrity. The Postgres engine blocks this schema change because existing orphaned data violates the constraint, throwing a fatal error.
Refer the Resolution and Workaround steps detailed in following kb to fix this issue: "Error attempting Upgrade Database Schema" during vCenter 8.0 U3x or 9.0.x to 9.1.0.0 upgrade
