PostgreSQL Connection URL Builder

pg-database-url is a minimalist utility that constructs a PostgreSQL connection string (URI) from a structured JavaScript configuration object. Released as version 0.1.0, this package targets older Node.js environments (specifically `>=4.2.0`) and exclusively uses CommonJS modules. As of the last observed activity, the project appears to be abandoned, with no significant updates or maintenance in recent years (last commit over 11 years ago). Its primary function is to simplify the creation of connection strings for use with PostgreSQL client libraries like `node-postgres`, converting host, port, database, username, and password into a standard `postgres://` URI format. It does not offer advanced features like connection pooling, query building, or extensive validation, focusing solely on the URI generation aspect. There are no clear release cadences or stated differentiators, as it is a very specific, single-purpose library.
