 <span class="shortdesc">GPORCA extends the planning and optimization capabilities of the HAWQ legacy optimizer. </span> GPORCA is extensible and achieves better optimization in multi-core architecture environments. When GPORCA is available in your HAWQ installation and enabled, HAWQ uses GPORCA to generate an execution plan for a query when possible.
 
 GPORCA also enhances HAWQ query performance tuning in the following areas:

 HAWQ devises a *query plan* for each query. Choosing the right query plan to match the query and data structure is necessary for good performance. A query plan defines how HAWQ will run the query in the parallel execution environment.

 This topic provides a referene of the character sets supported in HAWQ.
 
 The character set support in HAWQ allows you to store text in a variety of character sets, including single-byte character sets such as the ISO 8859 series and multiple-byte character sets such as EUC (Extended Unix Code), UTF-8, and Mule internal code. All supported character sets can be used transparently by clients, but a few are not supported for use within the server (that is, as a server-side encoding). The default character set is selected while initializing your HAWQ using `hawq init.` It can be overridden when you create a database, so you can have multiple databases each with a different character set.

 This topic provides a reference of the data types supported in HAWQ.
 
 HAWQ has a rich set of native data types available to users. Users may also define new data types using the `CREATE TYPE` command. This reference shows all of the built-in data types. In addition to the types listed here, there are also some internally used data types, such as **oid** (object identifier), but those are not documented in this guide.

 This section describes all server configuration guc/parameters that are available in HAWQ.
 
 Configuration guc/parameters are located in `$GPHOME/etc/hawq-site.xml`. This configuration file resides on all HAWQ instances and is managed either by Ambari or by using the `hawq config` utility. On HAWQ clusters installed and managed by Ambari, always use the Ambari administration interface, and not `hawq config`, to configure HAWQ properties. Ambari will overwrite any changes made using `hawq config`.

 This reference describes the HAWQ system catalog tables and views.
 
 System tables prefixed with '`gp_`' relate to the parallel features of HAWQ. Tables prefixed with '`pg_`' are either standard PostgreSQL system catalog tables supported in HAWQ, or are related to features HAWQ that provides to enhance PostgreSQL for data warehousing workloads. Note that the global system catalog for HAWQ resides on the master instance.

 The `gp_configuration_history` table contains information about system changes related to fault detection and recovery operations. The HAWQ [fault tolerance service](../../admin/FaultTolerance.html) logs data to this table, as do certain related management utilities such as `hawq init`. For example, when you add a new segment to the system, records for these events are logged to `gp_configuration_history`. If a segment is marked as down by the fault tolerance service in the [gp\_segment\_configuration](gp_segment_configuration.html) catalog table, then the reason for being marked as down is recorded in this table.
 
 The event descriptions stored in this table may be helpful for troubleshooting serious system issues in collaboration with HAWQ support technicians.

 The `gp_master_mirroring` table contains state information about the standby master host and its associated write-ahead log (WAL) replication process. If this synchronization process (`gpsyncagent`) fails on the standby master, it may not always be noticeable to users of the system. This catalog is a place where HAWQ administrators can check to see if the standby master is current and fully synchronized.

 The `gp_segment_configuration` table contains information about master, standby and segment configuration.
 
 The HAWQ fault tolerance service (FTS) automatically detects the status of individual segments and marks the status of each segment in this table. If a segment is marked as DOWN, the corresponding reason is recorded in the [gp\_configuration\_history](gp_configuration_history.html) table. See [Understanding the Fault Tolerance Service](../../admin/FaultTolerance.html) for a description of the fault tolerance service.

 The `pg_aggregate` table stores information about aggregate functions. An aggregate function is a function that operates on a set of values (typically one column from each row that matches a query condition) and returns a single value computed from all these values. Typical aggregate functions are `sum`, `count`, and `max`. Each entry in `pg_aggregate` is an extension of an entry in `pg_proc`. The `pg_proc` entry carries the aggregate's name, input and output data types, and other information that is similar to ordinary functions.

 The `pg_authid` table contains information about database authorization identifiers (roles). A role subsumes the concepts of users and groups. A user is a role with the `rolcanlogin` flag set. Any role (with or without `rolcanlogin`) may have other roles as members. See [pg\_auth\_members](pg_auth_members.html#topic1).
 
 Since this catalog contains passwords, it must not be publicly readable. [pg\_roles](pg_roles.html#topic1) is a publicly readable view on `pg_authid` that blanks out the password field.

 The `pg_cast` table stores data type conversion paths, both built-in paths and those defined with `CREATE CAST`. The cast functions listed in `pg_cast` must always take the cast source type as their first argument type, and return the cast destination type as their result type. A cast function can have up to three arguments. The second argument, if present, must be type `integer`; it receives the type modifier associated with the destination type, or `-1` if there is none. The third argument, if present, must be type `boolean`; it receives `true` if the cast is an explicit cast, `false` otherwise.
 
 It is legitimate to create a `pg_cast` entry in which the source and target types are the same, if the associated function takes more than one argument. Such entries represent 'length coercion functions' that coerce values of the type to be legal for a particular type modifier value. Note however that at present there is no support for associating non-default type modifiers with user-created data types, and so this facility is only of use for the small number of built-in types that have type modifier syntax built into the grammar.

 The system catalog table `pg_class` catalogs tables and most everything else that has columns or is otherwise similar to a table (also known as *relations*). This includes indexes (see also [pg\_index](pg_index.html#topic1)), sequences, views, composite types, and TOAST tables. Not all columns are meaningful for all relation types.

 The `pg_depend` system catalog table records the dependency relationships between database objects. This information allows `DROP` commands to find which other objects must be dropped by `DROP CASCADE` or prevent dropping in the `DROP RESTRICT` case. See also [pg\_shdepend](pg_shdepend.html#topic1), which performs a similar function for dependencies involving objects that are shared across a HAWQ system.
 
 In all cases, a `pg_depend` entry indicates that the referenced object may not be dropped without also dropping the dependent object. However, there are several subflavors identified by `deptype`:

 The `pg_filespace` table contains information about the filespaces created in a HAWQ system. Every system contains a default filespace, `pg_system`, which is a collection of all the data directory locations created at system initialization time.
 
 A tablespace requires a file system location to store its database files. In HAWQ, the master and each segment needs its own distinct storage location. This collection of file system locations for all components in a HAWQ system is referred to as a filespace.

 A tablespace requires a file system location to store its database files. In HAWQ, the master and each segment needs its own distinct storage location. This collection of file system locations for all components in a HAWQ system is referred to as a *filespace*. The `pg_filespace_entry` table contains information about the collection of file system locations across a HAWQ system that comprise a HAWQ filespace.

 The `pg_inherits` system catalog table records information about table inheritance hierarchies. There is one entry for each direct child table in the database. (Indirect inheritance can be determined by following chains of entries.) In HAWQ, inheritance relationships are created by both the `INHERITS` clause (standalone inheritance) and the `PARTITION         BY` clause (partitioned child table inheritance) of `CREATE       TABLE`.
