Why not the opposite ? Why do you insist to run obsolete/inferior patch 
level version ? Who want to run something older than the latest patch 
release of one maintained version and even more a more than ten patch 
level apart ?
The memory consomption diff is not an argument as it is simply 
ridiculous vs the used scenario.
Reproduce the 9.16.32 scenario, and if it reproduce Ondřej result, the 
conclusion will be evident : bugs in the older patch level as you 
clearly reproduced the 9.18 usage which you could surely reproduce with 
the 9.19 series too.
Do you really prefer to run buggy but less memory hungry version ?

I understand that you want to have answer to you questions. Simply do 
the complete exercise and you will have answers. Don't ask people to do 
them for you.

PS: there where a switch on the default runtime config switch to "big 
server" mode sometimes during the 9.16 series if I recall correctly. It 
perhaps explain the diff.
