Currently this version is still in development and the last commit fest will be in March. See more details here: https://wiki.postgresql.org/wiki/Submitting_a_Patch If you are willing to get something done in older versions, it may be interesting to look at the hook in elog.c and try to implement what you are looking for as plugin loaded by the server at startup using shared_preload_libraries. Reading roughly what you are writing above, I guess that it could be possible: the elog hook offers ways to redirect message strings generated by the server the way you want. I wrote such a thing some time ago to generate logs with a JSON format, you may want to look at that to give you more ideas: https://github.com/michaelpq/pg_plugins/tree/master/jsonlog -- Michael -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
