Thanks All,

It seems that the related DETAIL message appears if the query is successful.  On error the DETAIL log line is missing...   This makes debugging difficult, considering the insert is coming from Dreamfactory via a rest POST.   

I am finding it very difficult navigating my way through the brave new world of SAS and Blackbox type applications....  Maybe 32 years as a database programmer is just too long.

Thanks 

Andrew

Actually no:

https://www.postgresql.org/docs/10/static/runtime-config-logging.html#RUNTIME-CONFIG-LOGGING-WHEN

log_min_duration_statement (integer)

"... Setting this to zero prints all statement durations. Minus-one (the
default) disables logging statement durations.  ..."

"

So -1 only affects logging statements relative to duration.

If you have log_statements set then you will still get statements logged
if you have log_min_duration_statement = -1 :

Note

When using this option together with log_statement, the text of
statements that are logged because of log_statement will not be repeated
in the duration log message.
"

This is how I have my logging setup, log_min_duration_statement = -1
and log_statements = 'mod' and I see statements in the logs.
