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

Hi

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]](at)][host][:port][/[dbname][/[[table[/[column[,column...]*]]]|sql]]]

Example of usage:
psql pgsql://joe:p4zzw0rd(at)example(dot)org:2345/dbname

Where
Scheme: pgsql
Username: joe
Password: p4zzw0rd
Host: example.org
Port: 2345
Database: dbname

I have attached an example of how it could be implemented. It uses libpcre
RegEx to pass the dburl.

best regards
Hans
