The following documentation comment has been logged on the website:

Page: https://www.postgresql.org/docs/13/app-psql.html
Description:

There is a spurious space inside the documentation:
\set HISTFILE ~/.psql_history- :DBNAME
instead of
\set HISTFILE ~/.psql_history-:DBNAME

Commits

  1. doc: Simplify example of HISTFILE for psql

  2. Add space before :DBNAME for proper \set expansion.
