PostgreSQL Data File Read refers to the process of reading data from the data files in a PostgreSQL database. These data files include the base data files, which contain tables, indexes, and data of other objects in the database. Reading data from data files can become a bottleneck in the performance of the database, especially when the database is large and experiences a high volume of concurrent queries. Optimizing PostgreSQL Data File Read is essential to improve the performance of the database system and minimize the response time of queries.
