Zoltan Chovan commented on HIVE-22546:
--------------------------------------
[~ashutosh.bapat] thanks for the heads up! I guess schema changes like this are
harder to test than I thought. I'll assign HIVE-22663 to myself.

> In the latest postgresql schema
> (standalone-metastore/metastore-server/src/main/sql/postgres/hive-schema-4.0.0.postgres.sql)
> the following tables have lowercase table and column names:
> {code:java}
> aux_table
> compaction_queue
> completed_compactions
> completed_txn_components
> hive_locks
> materialization_rebuild_locks
> min_history_level
> next_compaction_queue_id
> next_lock_id
> next_txn_id
> next_write_id
> repl_txn_map
> runtime_stats
> txn_components
> txn_to_write_id
> txns
> write_set{code}
> As these tables are referenced from the Hive sys database, the queries to
> these tables will fail with a "Table not found" error.
> The problem is that the table and column names are not enclosed in quotes, so
> postgres will turn these identifiers into lowercase.
