[GENERAL] Feature proposal, DBURL: psql pgsql://joe:p4zzw0rd@example.org:2345/dbname

The dburl (or dburi) has become common to use by many systems connecting to a database. The feature is that one can pass all parameters in a string, which has similar pattern as http-URI do.

Especially when using psql in a script, having the credentials in one string is convenient.

The syntax could be:
  [scheme[<+>dsn]]://[[username[:[password]]@][host][:port][/[dbname][/[[table[/[column[,column...]*]]]|sql]]]

Example of usage:
  psql pgsql://joe:p4zzw0rd@example.org:2345/dbname

Where

  Scheme: pgsql

  Username: joe

  Password: p4zzw0rd

  Host: example.org

  Port: 2345

  Database: dbname
