pgsizeprettypgdatabasesizemydb

pgsizeprettypgdatabasesizemydb is a command-line utility designed to provide a human-readable representation of PostgreSQL database sizes. It is a wrapper around the psql command, specifically utilizing its `\l` command to list databases and then processing the output to display sizes in a more understandable format, such as megabytes (MB) or gigabytes (GB). This contrasts with the raw byte counts often returned by default database size queries.

The primary function of pgsizeprettypgdatabasesizemydb is to simplify the task of quickly assessing the disk space occupied by individual PostgreSQL databases within a server. Users can typically invoke the tool with minimal arguments, and it connects to the specified PostgreSQL instance to retrieve the necessary information. The output is usually presented as a list of databases, each with its corresponding size formatted for easy comprehension. This makes it a convenient tool for database administrators or developers who need to monitor storage consumption across multiple databases without manual calculation or complex query construction.

While the exact implementation details might vary, the core purpose remains consistent: to enhance the readability of PostgreSQL database size information. This can be particularly useful in environments with many databases or when performing regular disk usage audits. The tool generally assumes that psql is installed and configured for the target PostgreSQL server.
