Обсуждение: [GENERAL] 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]]@][host][:port][/[dbname][/[[table[/[column[,column...]*]]]|sql]]]
[scheme[<+>dsn]]://[[username[:[password]]@][host][:port][/[dbname][/[[table[/[column[,column...]*]]]|sql]]]
Where
Scheme: pgsql
Username: joe
Password: p4zzw0rd
Host: example.org
Port: 2345
Database: dbname

You connect to a database, not to a table. Thomas

Sorry! I did not read the *new* manual.
(OK, 9.2 is not that new)
It is even mentioned in the man page.
Then I have a new proposal. Write a note about in
psql --help

Besides the fact that something like that is already possible:
What's the use of "table" and "column" in the URI? You connect to a database, not to a table.
With 'table' the idea was to do a "SELECT * FROM table" on that.
With 'column' added only that or those columns would be listed.
The "sql" part in the end was supposed to be a SQL-statement to be executed, like:
psql "postgresql://localhost/dbname/INSERT INTO foo VALUES($RANDOM)"
which should be equal to
echo "INSERT INTO foo VALUES($RANDOM)" | psql postgresql://localhost/dbname

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The thing is that in a quick search on this I did not find a reference implementation of this to compare against.
"dsn" is only relevant when the scheme is ODBC.
In a situation where an application (like Drupal) get connect string (URI) it should be able to find the right driver to use. In case with of ODBC, a dsn (Data Source Name) is needed.

That was formatting error on my part, I was trying to point to the back half of the URI.
