This is evidently a bug in libreadline or libedit (whichever you're
using), and almost certainly has nothing to do with psql proper.
The mention of el_gets() in the stack trace makes me suspect that it's
libedit, which is not terribly surprising because frankly we've seen a
darn lot of nasty bugs in that library. They do fix 'em, so you could try
getting a newer version of libedit. Or you could get GNU readline and
rebuild against that. TBH I'd recommend the latter solution.
