What is pg-connection-string?
The pg-connection-string package is a utility for parsing PostgreSQL connection strings. It can parse a connection string into an object with configuration details, which can then be used to establish a connection to a PostgreSQL database. This is particularly useful when working with environment variables or configuration files that store database connection information in a URI format.
What are pg-connection-string's main functionalities?
Parsing connection string
This feature allows you to parse a PostgreSQL connection string into a configuration object. The object includes properties such as user, password, host, port, and database, which can be used to establish a connection to a PostgreSQL database.
const { parse } = require('pg-connection-string');
const config = parse('postgres://user:password@localhost:5432/database');
console.log(config);

float8 | number (float) | string
int8 | string | number (int)
numeric | string | number (float)
decimal | string | number (float)

If you are unhappy with these changes you can always override the built in type parsing fairly easily.
