Hello,
if there is no consensus, on whether --lines should substitute a
separate entry in the history, then make it an .psqlrc/CLI option.
For psql/HISTSIZE, please update the documentation to state, that
HISTSIZE -1 disables the file truncation.
About the concerns with rl_variable_bind("comment-begin", "--")
regarding libreadline/libedit versions: you can put the change only on
master and announce it for Pg10. If nobody objects within a year, this
can be backported.
Greetings Дилян
