If interested I have somewhere pl/pythhonu functions for both looking at
and
changing parameters in postgresql.conf file,

It even keeps the old value and adds comments both to old and to the new
one abot who an when changed it.
Could also be extended to fpr example rotate last 10 postgreSQL conf
files and/or skip rewriting the file in case the effective value of GUC
did not change.
