Based on user feedback, I discuss the most requested features for PostgreSQL, their implementation status, difficulties, blockers, and future plans. Items include replication, materialized views, parallel queries, in-place upgrade.
SQL/MED provides methods to access non-SQL data from SQL. It includes a wrapper interface that allows defining foreign tables on foreign servers accessed through foreign data wrappers. It also includes datalinks to manage files referenced from a database. PostgreSQL 8.4 includes initial SQL/MED support and substantial additional support is planned for 8.5, including writing wrapper libraries and foreign table support.
SQL/MED is Management of External Data, a part of the SQL standard that deals with how a database management system can integrate data stored outside the database. The implementation of this specification has begun in PostgreSQL 8.4 and will over time introduce powerful new features into PostgreSQL.

Using Delta Lake to Transform a Legacy Apache Spark to Support Complex Update...Databricks
The convergence of big data technology towards traditional database domain has became an industry trend. At present, open source big data processing engines, such as Apache Spark, Apache Hadoop, Apache Flink, etc., already support SQL interfaces, and the usage of SQL basically occupies a dominant position. Companies use above open source software to build their own ETL framework and OLAP technology. However, in terms of OLTP technology, it is still a strong point of traditional databases. One of the main reasons is the support of ACID by traditional databases.
Liquibase få kontroll på dina databasförändringarSqueed
You never develop code without version control, why do you develop your database without it? With Liquibase, database changes are stored in human XML-files and committed to the source control system. Changes are applied to the developers local databases. As changes are committed they are distributed to all other environments including all developers local databases, test databases, staging databases, and even to production databases. This presentation will introduce you to Liquibase and the topic database change management. We will also present some advanced topics based on real life experience and a few tips and tricks as well

Similar to Most Wanted: Future PostgreSQL Features (20)
This document discusses using Python to connect to and interact with a PostgreSQL database. It covers:
- Popular Python database drivers for PostgreSQL, including Psycopg which is the most full-featured.
- The basics of connecting to a database, executing queries, and fetching results using the DB-API standard. This includes passing parameters, handling different data types, and error handling.
- Additional Psycopg features like server-side cursors, transaction handling, and custom connection factories to access columns by name rather than number.
In summary, it provides an overview of using Python with PostgreSQL for both basic and advanced database operations from the Python side.
This document provides an overview of PL/Proxy, a database partitioning system implemented as a PostgreSQL procedural language extension. PL/Proxy allows applications to perform database operations like inserts, updates, deletes and queries across multiple PostgreSQL database partitions in a transparent manner. It works by routing operations to the appropriate partition based on the value of a partitioning key. The document discusses PL/Proxy concepts, areas of application, example usage, installation, backend and frontend functions, configuration options and more.
Is putting archives of binaries on a CD image still the way to serve the users? In the face of the likes of Google and Amazon impacting the way
users interact with software and systems, and eroding the four freedoms, how can Linux distributions keep up? Distribute QEMU images? Write a free GMail clone? Offer community-managed web email hosting? Can this work, and who is going to pay for it?
Porting Oracle applications to PostgreSQL can be difficult due to differences in SQL syntax, data types, functions, and PL/SQL implementations between the databases. While many elements like table definitions and queries may port easily, issues arise with data types, functions, outer joins, null values, triggers, date/time handling, and PL/SQL syntax. A full rewrite may be preferable to porting in many cases. Careful evaluation and planning is needed to determine the best approach.
The document discusses PostgreSQL's current and future support for XML. It outlines current features like the XML data type, XML publishing functions, XML export, and XPath support.

Several examples are provided to illustrate current XML functionality in PostgreSQL.
This document summarizes Peter Eisentraut's presentation on XML support in PostgreSQL. It discusses the types of XML support including an XML data type, XML export format, and mapping XML documents to SQL databases. It also outlines specifications like SQL/XML, features of the XML data type, functions for input, output, and querying XML, and the status and future of XML support in PostgreSQL.

The document discusses current and future developments related to XML support in PostgreSQL. It describes current features like the XML data type, XML publishing functions, and XML export functions. Future plans include adding XPath support and further developing areas like XML validation, indexing XML data, and XQuery support to comply with SQL standards. The goal is to improve PostgreSQL's capabilities for storing, querying, and exporting XML content and schemas.
This document summarizes PL/Java, which allows writing server-side functions in Java for PostgreSQL. It discusses how to define and deploy Java functions, configure PL/Java, handle parameters and return types, use JDBC from functions, and write triggers in Java. While compatible with Oracle's SQL/JRT standard, PL/Java has some limitations around memory usage and performance. It works best on Linux and is a stable option for adding Java code to PostgreSQL databases.
This document discusses various goals, techniques, and solutions for replicating PostgreSQL databases. The goals covered are high availability, performance for reads and writes, supporting wide area networks, and handling offline peers. Techniques include master-slave and multi-master replication, proxies, and using standby systems. Specific solutions described are Slony-I, Slony-II, PGCluster, DBMirror, pgpool, WAL replication, Sequoia, DRBD, and shared storage. The document provides an overview of how each solution can help achieve different replication goals.
PostgreSQL 8.1 was recently released with hundreds of changes and new features including:
1) Bitmap scans allow using more than one index per table by combining index hits in memory.
2) Two-phase commit support allows prepared transactions to be preserved across server restarts.
3) The new role system unifies users and groups and roles can own database objects.
4) Constraint exclusion avoids lookups on child tables when constraints make rows impossible.
Collateral Damage: Consequences of Spam and Virus Filtering for the E-Mail Sy...Peter Eisentraut
The document discusses the collateral damage caused by spam and virus filtering techniques. It analyzes various techniques like DNS blacklists, bounce messages, greylisting, SPF, blocking port 25, and challenge-response systems. Many techniques are found to be ineffective against spam, annoy users, violate privacy, or break functionality. It warns against inventing your own filters and notes legal issues around privacy, database building, and user consent with filtering. The conclusion is that email reliability has decreased due to both spammers and inappropriate filter applications.

The Common Debian Build System (CDBS) provides makefile fragments to simplify Debian package building. It includes classes that handle common build systems like autotools and distutils. CDBS aims to standardize packaging and automatically implement policy changes. While it helps most packages, it may be unnecessary for simple packages or those with unusual build systems. CDBS maintenance involves addressing bugs, feature requests, outdated documentation, and ensuring compatibility with Debian subpolicies.
Cosa hanno in comune un mattoncino Lego e la backdoor XZ?Speck&Tech
ABSTRACT: A prima vista, un mattoncino Lego e la backdoor XZ potrebbero avere in comune il fatto di essere entrambi blocchi di costruzione, o dipendenze di progetti creativi e software. La realtà è che un mattoncino Lego e il caso della backdoor XZ hanno molto di più di tutto ciò in comune.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
