pgsizepretty

pgsizepretty is a command-line utility designed to make PostgreSQL database size information more human-readable. It parses the output of the standard PostgreSQL command `psql` when run with specific options to display table and index sizes in a formatted way. Instead of raw byte counts, pgsizepretty presents sizes in common units like KB, MB, and GB, making it easier to quickly assess storage usage within a database. The tool is particularly useful for database administrators and developers who need to monitor disk space consumption and identify large tables or indexes that might require optimization. Its primary function is to enhance the output of existing PostgreSQL tools, offering a more user-friendly perspective on database resource allocation. It typically operates by taking the output of a `psql` query as its input and then reformatting it. This allows users to integrate pgsizepretty into their existing PostgreSQL workflows without significant disruption. The utility is often found in open-source repositories and can be installed and used alongside PostgreSQL installations.
