Hi All,

I changed the postgresql.conf file (of an 8.2.4 server), and issued
relaod using pg_reload_config(). Following are the messages I see in the log
files:

May 14 21:38:40 sfphotodb001 postgres[29658]: [19-1] 2008-05-14 21:38:40
PDTLOG: received SIGHUP, reloading configuration files
May 14 21:38:40 sfphotodb001 postgres[29658]: [20-1] 2008-05-14 21:38:40
PDTLOG: parameter "shared_buffers" cannot be changed after server start;
configuration file change ignored
May 14 21:39:03 sfphotodb001 postgres[22928]: [21-1] 2008-05-14 21:39:03
PDTLOG: archived transaction log file "0000000100000E23000000C8"

What's confusing about this is that the second message says
'configuration file change ignored', so I expect the changed (newly enabled)
archive_command to not take effect. But in fact, it does take effect.

The message probably should be rephrased to say that this setting
(shared_buffers) will not be changed.

Best regards,
