>             Project: Hive
>          Issue Type: Bug

>    Affects Versions: 0.12.0
>         Environment: Ubuntu 12.04
> PostgreSQL 9.1.8

> Some operations against the Hive Metastore seem broken
> against Postgres.
> For example, when using HiveMetastoreClient.listPartitions()
> the Postgres logs show queries such as:
> 2013-09-09 19:10:01 PDT STATEMENT:  select PARTITIONS.PART_ID from
> PARTITIONS  inner join TBLS on PARTITIONS.TBL_ID = TBLS.TBL_ID   inner
> join DBS on TBLS.DB_ID = DBS.DB_ID  where TBLS.TBL_NAME = $1 and
> DBS.NAME = $2 order by PART_NAME asc
> with a somewhat cryptic (but correct) error:
> ERROR:  relation "partitions" does not exist at character 32
> Postgres identifiers are somewhat unusual. Unquoted identifiers are 
> interpreted as lower case (there is no Postgres option to change this). Since 
> the Metastore table schema uses upper case table names, the correct SQL 
> requires escaped identifiers to those tables, i.e.,
> select "PARTITIONS"."PART_ID" from "PARTITIONS"...
> Hive sets metastore.try.direct.sql=true by default, so the above SQL is 
> generated by hive/metastore/MetaStoreDirectSql.java, i.e., this is not a 
> Datanucleus problem.
> When I set metastore.try.direct.sql=false, then the Metastore backed by 
> Postgres works.
