Greetings, I have recent problem that I can't explain. I had 7.0_STABLE (GENERIC) box, which was recently upgraded to 7.1_STABLE.
It seems that PostgreSQL 9.5 may not continue working anymore, saying FATAL: could not open shared memory segment "/PostgreSQL.1804289383": Not supported I booted old kernel back and it work as it should. I can't explain that, besides: 1. I definitely have lot of 7.1_STABLE boxes with PostgreSQL 9.5 or 10 working well. 2. PostgreSQL have no special tweaks about memory, so this is not related to shm parameters. -- Sincerely yours, Dima Veselov Physics R&D Establishment of Saint-Petersburg University
