Обсуждение: postgres hab modification without restarting
Hi all! Is it possible to make the postmaster re-read the pg_hba.conf when needed without pg_ctl restarting the database? I think I could send a unix signal to it, it would simly re-read the file and apply the information for new incoming connection requests. I was looking for this info in the documentation and lists but I did not find anything. Thanks, Laszlo

Ok, I know this was an RTFM category question, I just didn`t find the information, but I promiss I will learn more about the proper use of the unix command 'grep', so next time I will find it easily :) I was looking for a `crontab -e`-like editing. It lets edit the file, checks the format, and installs if changed, doesn`t let user make failure - for example to forget sending the signal, or writing bad formated pg_hba.conf. Is there something like that?
