Description

Hive metastore schema on postgres is broken after the commit for HIVE-14498. Following error is seen during schema initialization:

0: jdbc:postgresql://localhost.localdomain:54> ALTER TABLE ONLY "MV_CREATION_MET
ADATA" ADD CONSTRAINT "MV_CREATION_METADATA_FK" FOREIGN KEY ("TBL_ID") REFERENCE
S "TBLS"("TBL_ID") DEFERRABLE
Error: ERROR: there is no unique constraint matching given keys for referenced table "TBLS" (state=42830,code=0)
Closing: 0: jdbc:postgresql://localhost.localdomain:5432/hive

*** schemaTool failed ***

In the file metastore/scripts/upgrade/postgres/hive-schema-3.0.0.postgres.sql the ordering of statement

ALTER TABLE ONLY "MV_CREATION_METADATA"
 ADD CONSTRAINT "MV_CREATION_METADATA_FK" FOREIGN KEY ("TBL_ID") REFERENCES "TBLS"("TBL_ID") DEFERRABLE;

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