I don't think this is a bug. The history file is read at psql startup
and written out (to the same file name) at exit. Those operations are
quite expensive, so it would be insane to do them after every backslash
command on the off chance that somebody was expecting to have changed
the effective name of the history file. (Aside from the cost, this
would greatly increase the race condition hazards from concurrent psql
sessions trying to write the file at the same time.)
