Hi all, postgresql.conf says: # This file is read on postmaster startup and when the postmaster # receives a SIGHUP. If you edit the file on a running system, you have # to SIGHUP the postmaster for the changes to take effect, or use # "pg_ctl reload".
Does that mean I can just use "pg_ctl reload" to let the changed parameters take affect? Or do I have to restart postgres? Or only some parameters can be taken affect by "pg_ctl reload" (if this case, what are they)? Same question from man page of pg_ctl: pg_ctl reload - simply sends the postmaster a SIGHUP signal, causing it to reread its configuration files (postgresql.conf, pg_hba.conf, etc.). This allows changing of configuration-file options that do not require a complete restart to take effect. The problem is which options do not require a complete restart and which ones do?
