Bug reference:      15076
Logged by:          Mingchun Zhao
Email address:      mzhao@insight-tec.co.jp
PostgreSQL version: 9.3.20
Operating system:   Windows
Description:

steps to reproduce:

(1) run psql.exe in a Windows Command Prompt
(2) execute a SQL with more than one page of results, e.g. `show all;`
(3) press Ctrl + C to break it on the first page
(4) press up arrow key to try to execute the previous SQL of the step(2)
again
(5) Occasionally, it will show you nothing about the SQL, then you can try
to input a character ';' and press Enter key, the PostgreSQL will crash
unexpectedly

It would help to explain what you actually see in step 5 instead of just saying crash.  In particular is the "failure" in the server or client?
