Posted April 07, 2018 04:13:54If you’re not familiar with PostgreSQL, here’s a quick refresher:PostgreSQL is a database system built to store, analyze, and query large amounts of data in real-time, using modern programming languages.
The system can be used to build real-world applications, such as web-based web servers or big data analytics applications.
PostgreSQL has become a favorite among researchers because of its performance, scalability, and high reliability, among other attributes.
In the next section, we’ll learn how to write the following SQL statements:With PostgreSQL 9.4, the company introduced a new data-driven architecture, called the Data Driven Development (DDD) model.
While the new architecture allows for more flexibility in how and when data is processed, it also introduces new features like a new SQL statement parser and new database features.
The new features introduced in PostgreSQL 11.1 are named PostgreSQL Statement Parser and Database Features.
PostgreSQL developers introduced the new features to help new users and developers make the most of the new data types in Postgres, which are defined as data types that are built upon top of other types.
To make these features work, developers need to understand PostgreSQL statements better, especially when dealing with data types like lists and tuples.
The PostgreSQL statement parser is used to parse PostgreSQL SQL statements into more readable and readable formats.
For example, you can write the query below to see what data types are supported:As you can see, the parser parses a SQL statement like the following:With this parser, PostgreSQL has defined the following data types:To see what types PostgreSQL supports, look at the following table:As of PostgreSQL 10.1, the following list of types has been added to the PostgreSQL specification:This makes it possible to write queries like the query above to find out how many lists are in a particular database:Now that we’ve learned how to use the new statement parser to parse SQL statements, we can also see the following two data types (list types) in the parser:If you want to understand how to create a new statement with the statement parser, here are some links:The next section is a good place to learn about the new database feature, Database Features, which is described in more detail in the next two sections.
