The current version of PostgreSQL, v14, adds additional support for complex data types and JavaScript Object Notation (JSON) unstructured data. PostgreSQL comes with several features for boosting and optimizing performance. For these types of applications, performance is a major factor. PostgreSQL is being widely adopted across several industries and is commonly used for data warehousing and highly transactional, complex applications that require large volumes of data. Why Is PostgreSQL Performance So Important?

Two functions are used to implement PostgreSQL Full Text Search: Full Text Search indexes documents for faster search results and supports dictionaries for finer control over token normalization. While the LIKE and ILIKE clauses can perform string search queries, the words in the text are not indexed, resulting in performance penalties. It can also identify natural-language documents that meet the requirements of a query and sort them by relevance to the query. PostgreSQL Full Text Search allows you to search for a single document or a collection of documents in a full-text database. While PostgreSQL is the official name, Postgres is an accepted nickname, and PostgreSQL is now commonly referred to as Postgres.
In 1996, when the name Postgres95 became obsolete, PostgreSQL was chosen as the new name to reflect the original POSTGRES project and the added support for SQL.

After the POSTGRES project ended in 1993, Postgres95 was built on top of POSTGRES code in 1995 and a SQL language interpreter was added as a replacement for the query language PostQUEL. PostgreSQL derives from the POSTGRES project started at the University of California at Berkeley in 1986.

When creating new objects like tables, if no schema name is specified, the table will be created in the current schema. The first schema returned in the search path is called the current schema. The PostgreSQL search_path variable allows you to determine the order in which schemas are searched and which schemas don’t need to use schema qualification. Remote clients can connect to the server over the network or the internet. The server program manages database files and accepts and executes multiple concurrent connections to the database from client applications. PostgreSQL uses a client-server architecture that allows the client and server to reside on different hosts on the network. PostgreSQL has become the preferred open source relational database of many organizations. With over 30 years of active development and the support of a dedicated open source community, PostgreSQL competes with top-ranked commercial databases such as SQL Server and Oracle. Its primary functions are to store and retrieve data securely while supporting current computing best practices. PostgreSQL is an open source object-relational database management system (ORDBMS) with a strong reputation for reliability and performance.
