Unknown Facts About Postgresql


PostgreSQL's Origins

While many people are aware that PostgreSQL originated from the POSTGRES project at the University of California, Berkeley, not everyone knows that the name "PostgreSQL" was adopted later to highlight its support for SQL. The "Post" in PostgreSQL refers to its support for Post-Ingres features and is not an acronym.

MVCC for Concurrency

PostgreSQL's Multi-Version Concurrency Control (MVCC) is a powerful feature that allows for concurrent access to data without locking. What's interesting is that MVCC enables each transaction to see a snapshot of the database at the start of the transaction, providing a high level of isolation and improving overall system concurrency.

Geospatial Capabilities with PostGIS

PostgreSQL is not just a relational database; it also excels in handling geospatial data. The PostGIS extension adds support for geographic objects, making PostgreSQL a go-to choice for applications requiring geospatial functionalities, such as mapping and location-based services.


Table Inheritance

PostgreSQL supports table inheritance, a feature that allows a table to inherit columns and properties from another table. This is a powerful mechanism for creating more abstract and organized database structures, particularly useful in scenarios where multiple tables share common attributes.

Full-Text Search

PostgreSQL includes a powerful and often overlooked full-text search engine. It enables developers to perform efficient and flexible searches on textual data, making it suitable for applications that require advanced search capabilities, such as content management systems or document repositories.

Foreign Data Wrappers

PostgreSQL's Foreign Data Wrapper (FDW) feature enables the integration of data from external sources seamlessly. With FDWs, you can query and join data from other PostgreSQL databases or even from non-PostgreSQL databases, treating them as if they were local tables.


Array Types

While many databases support basic data types, PostgreSQL takes it a step further by providing support for arrays of these types. This means you can have columns that store arrays of values, offering a convenient way to handle collections of data within a single database column.

JSONB Data Type

Beyond supporting JSON as a data type, PostgreSQL introduced JSONB (Binary JSON), a more efficient and performant way to store and query JSON data. JSONB not only maintains the hierarchical structure of JSON but also provides indexing for faster retrieval.

Custom Aggregates and Window Functions

PostgreSQL allows users to create custom aggregates and window functions, providing a high level of extensibility in data processing. This enables developers to define specialized calculations that can be seamlessly integrated into SQL queries, enhancing the expressive power of PostgreSQL.
