All of these names correspond to internal routines in libreadline.
It'd not be surprising for libreadline to suck a good deal of the
runtime of psql ... but I don't believe the backend will call it at all.
So, either this trace is erroneous, or you profiled the wrong process
(client instead of backend), or there's something truly weird going on.
