> Hive won't store anything in *TAB_COL_STATS* for partitioned table, whereas impala stores complete column stats in TAB_COL_STATS for partitioned table. Deleting entries in TAB_COL_STATS is based on (DB_NAME, TABLE_NAME), not by TBL_ID. Renamed tables were having old names in TAB_COL_STATS.
> To Repro:
> {code:java}
> beeline:
> set hive.create.as.insert.only=false;
> set hive.create.as.acid=false;
> create table testes.table_name_with_partition (id tinyint, name string) partitioned by (col_to_partition bigint) stored as parquet;
> insert into testes.table_name_with_partition (id, name, col_to_partition) values (1, "a", 2020), (2, "b", 2021), (3, "c", 2022);
> impala:
> compute stats testes.table_name_with_partition; -- backend shows new entries in TAB_COL_STATS
> beeline:
> alter table testes.table_name_with_partition rename to testes2.table_that_cant_be_droped;
> drop table testes2.table_that_cant_be_droped; -- This fails with TAB_COL_STATS_fkey constraint violation.
> {code}
> Exception trace for drop table failure
> {code:java}
> Caused by: org.postgresql.util.PSQLException: ERROR: update or delete on table "TBLS" violates foreign key constraint "TAB_COL_STATS_fkey" on table "TAB_COL_STATS"
>   Detail: Key (TBL_ID)=(19816) is still referenced from table "TAB_COL_STATS".
