Hi
one 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.
Regards
Pavel
