I think the idea of \conninfo+ printing multiple tables is setting up
the patch for failure. It is just too unusual. (Yes, I know "\d *" and
such can print multiple tables. That one is a disaster, perhaps the
worst psql command of all.) Also, in v36 you can specify another
character as second argument to display only one of the several tables.
How are users going to remember which is which? Most likely, they
won't.
v35 seems fine to me from a UI standpoint; I suggest we move forward
with that.
This is what I get with v36 on an unencrypted local connection:
55432 18devel 17266=# \conninfo+
Connection Information

Meanwhile, here's v35:
55432 18devel 20356=# \conninfo+
Connection Information
─[ RECORD 1 ]────────┬─────────
Base de Datos │ alvherre
Authenticated User │ alvherre

Socket Directory │ /tmp
Port │ 55432
Protocol Version │ 3
SSL Connection │ false
GSSAPI Authenticated │ false
Client Encoding │ UTF8
Server Encoding │ UTF8
Backend PID │ 20356
Or, if expanded mode is disabled, I get this
Connection Information
Base de Datos │ Authenticated User │ Session User │ Socket Directory │ Port │
Protocol Version │ SSL Connection │ GSSAPI Authenticated │ Client Encoding │
Server Encoding │ Backend PID
───────────────┼────────────────────┼──────────────┼──────────────────┼───────┼──────────────────┼────────────────┼──────────────────────┼─────────────────┼─────────────────┼─────────────
alvherre │ alvherre │ alvherre │ /tmp │ 55432 │
3 │ false │ false │ UTF8 │
UTF8 │ 29553
(1 fila)
(If Dean get his "backslash-command-expanded" patch in, we'd get
\conninfo+x for expanded mode here, and avoid the need to have "\x auto"
in .psqlrc)
