In the file metastore/scripts/upgrade/postgres/hive-schema-3.0.0.postgres.sql
the ordering of statement
{noformat}
ALTER TABLE ONLY "MV_CREATION_METADATA"
ADD CONSTRAINT "MV_CREATION_METADATA_FK" FOREIGN KEY ("TBL_ID") REFERENCES

is before the definition of unique constraints for TBLS which is causing the
issue.
