Hi, I'm not sure about mmap approach, it would just bring another
problems. I like the dsm approach because it's not inventing any new
files in the database, when mmap approach will possibly require new
folder in data directory and management above bunch of new files, with
additional issues related with pg_upgrade and etc. Also in dsm approach
if someone needs to update dictionaries then he (or his package
manager) can just replace files and be done with it.
