Subject: pgsql: Add local-address escape "%L" to log_line_prefix.
Date: Mon, 07 Apr 2025 15:06:17 +0000
Message-ID: <E1u1o3F-0038Vk-1v@gemulon.postgresql.org> (raw)
Add local-address escape "%L" to log_line_prefix.
This escape shows the numeric server IP address that the client
has connected to. Unix-socket connections will show "[local]".
Non-client processes (e.g. background processes) will show "[none]".
We expect that this option will be of interest to only a fairly
small number of users. Therefore the implementation is optimized
for the case where it's not used (that is, we don't do the string
conversion until we have to), and we've not added the field to
csvlog or jsonlog formats.
