Hi David,

sorry, absolutely forgot about important stuff like version.
Original problem has been found on 9.4.9, but I was able to reproduce it on 10rc1.

localhost/postgres=# select version();
                                                     version                                                    
─────────────────────────────────────────────────────────────────────────────────────────────────────────────────
 PostgreSQL 10rc1 on x86_64-pc-linux-gnu, compiled by gcc (Ubuntu 5.4.0-6ubuntu1~16.04.4) 5.4.0 20160609, 64-bit
