I don't get the the "DEBUG: parse tree:" or the DETAIL lines at all. I
restarted via pg_ctl. I assume that that's the same as reload.
Actually, if I set client_min_messages to 'debug1' via the SET command
in psql, then I get the detail information in my client. But I want the
information in my syslog, not my client. (My client's driver will barf
if I try to send the information there.) I wonder if their is too much
information and syslog being UDP never gets the detail line? (But then
it appears that postgresql is specifically breaking most longer
messages up into multiple lines, so I doubt this is it either.)
Thanks.
