Hione visitor of p2d2 (Prague PostgreSQL Developer Day) asked if it is possible to show the current role in psql's prompt. I think it is not possible, but fortunately (with some limits) almost all necessary work is done, and the patch is short.In the assigned patch I implemented a new prompt placeholder %N, that shows the current role name.(2023-02-03 15:52:28) postgres=# \set PROMPT1 '%n as %N at '%/%=%#
pavel as pavel at postgres=#set role to admin;
SET
pavel as admin at postgres=>set role to default;
SET
pavel as pavel at postgres=#Comments, notes are welcome.RegardsPavel
This patch is cluttered with the BACKEND_PID patch and some guc_tables.c stuff that I don't think is related.
We'd have to document the %N.
I think there is some value here for people who have to connect as several different users (tech support), and need a reminder-at-a-glance whether they are operating in the desired role. It may be helpful in audit documentation as well.
