as best i know, with the standard postgresql installations, there is no
component that modifies the pg_hba.conf file.

from the systems perspective, it is a static config file, like postgresql.conf

some external script/facility/action is updating your pg_hba.conf file,
and that external script/facility/action is likely unique to your environment,
os installation, server management facilities.

if the timestamp of the file is being set to the same time every day, you
might check the following files:
(may or may not be on your system)

/etc/crontab
/etc/cron.d/*
/var/cron/crontab/*
/var/spool/cron/crontab/*

grep for the timestamp in:
/var/log/cron*
/var/log/auth* (remote system automatically doing sysadmin via ssh?)
