RE: Psql meta-command conninfo+

SELECT

...

  current_user AS "User",

  This will be inconsistent with \conninfo.  \conninfo returns authenticated user (PQuser), not the current_user.  It might be worth showing current_user, session_user, and authenticated user,  but I can't find the appropriate sql function for PQuser.    What about to include system_user function? It shows useful authentication details.
  Also, it seems that the verbose parameter in the listConnectionInformation  is unnecessary.

Hi,

Tks Pavel.

Analyzing the functions' code more thoroughly, it seems to make more sense.
I liked your suggestions and implemented them for validation.
Regarding "system_user," I believe it is valid and also added it to the row.

"Also, it seems that the verbose parameter in the listConnectionInformation is unnecessary."
Could you point out exactly the line or code snippet you are referring to?

To print the string from the "Authenticated User" column, I chose to use PQuser(pset.db) directly. I did the same for the "Host" column, opting for PQhost(pset.db). This does not contradict the result of \conninfo.

Here are the tests as usual, and v6 patch.
