cgit clone git://git.postgresql.org/git/postgresql.git cd postgresql git branch -r git checkout -b origin/REL9_6_STABLE9.6.17 was released in February 2020. I was a bit curious about this commit before pushing it
commit 93745f1e019543fe7b742d0c5e971aad8d08fd56 Author: Thomas MunroUsing the link above then I got all details I want.Date: Sat Feb 1 14:29:13 2020 +1300 Fix memory leak on DSM slot exhaustion. If we attempt to create a DSM segment when no slots are available, we should return the memory to the operating system. Previously we did that if the DSM_CREATE_NULL_IF_MAXSEGMENTS flag was passed in, but we didn't do it if an error was raised. Repair. Back-patch to 9.4, where DSM segments arrived.
