BUG #11477: psql -L no stderr

The following bug has been logged on the website:

Bug reference:      11477

Operating system:   Centos 6.5
Description:

Hello!

Command
psql -L logfile
logs only stdout (formated with stars) but not stderr.

Command
psql -L logfile 2>logfile
logs also warnings/errors but does not write them to terminal.

Command
psql 1>&2 |tee logfile
writes both to terminal and file but without stars formatting.

I am sorry, but log without errors logging is NOT a log file. I consider not
logging stderr to logfile when -L is specified as a bug.

Please add coppying also stderr to logfile when -L.

Thank you
