> Key: HIVE-23576
> URL: https://issues.apache.org/jira/browse/HIVE-23576
> Project: Hive
> Issue Type: Bug

> Affects Versions: 3.1.2
> Environment: metastore db - postgres (tried on 9.3 and 11.5)

> # +pgiven the following situation:+
> there are 2 tables (in db "intpartitionbugtest"), each with a few rows:
> # *test_table_int_1* partitioned by *y* of type *int*
> # *test_table_string_1* partitioned by *x* of type *string*
> here is the output of the following query on the metastore db:
> {code:sql}
> select
> "PARTITIONS"."PART_ID",
> "TBLS"."TBL_NAME",
> "FILTER0"."PART_KEY_VAL",
> "PART_NAME"
> from
> "PARTITIONS"
> inner join "TBLS" on
> "PARTITIONS"."TBL_ID" = "TBLS"."TBL_ID"
> inner join "DBS" on
> "TBLS"."DB_ID" = "DBS"."DB_ID"
> inner join "PARTITION_KEY_VALS" "FILTER0" on
> "FILTER0"."PART_ID" = "PARTITIONS"."PART_ID"
> {code}
>

> +the problem+
> when running a hive query on the table *test_table_int_1* that filters on
> *y=1*
> sometimes the following exception will happen on the metastore
>
> {code:java}
> javax.jdo.JDODataStoreException: Error executing SQL query "select
