Data Types in PostgreSQL

PostgreSQL offers a comprehensive set of data types to cater to diverse data needs, including numeric types like INTEGER, FLOAT, and SERIAL for auto-incrementing fields; character types such as VARCHAR and TEXT for variable-length text; and temporal types like DATE, TIME, and TIMESTAMP for handling date and time data. Additionally, PostgreSQL supports BOOLEAN for true/false values, ENUM for enumerated lists, and composite types for complex structures. It also excels with JSON and JSONB for storing and querying semi-structured data, arrays for storing multiple values in a single field, and geometric types for spatial data. These data types ensure flexibility and robust data management for various applications.
