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

pg_ctl reload sends the signal to reread the config files
http://www.postgresql.org/docs/7.3/interactive/app-pg-ctl.html

some parameters can only be set at server start
http://www.postgresql.org/docs/7.3/interactive/runtime-config.html

I think the 'postgres' manual page explains the actual signals used.

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?
