From 6e0cb3dec10e460288d68a128e3d79d16a230cdb Mon Sep 17 00:00:00 2001 From: Fujii Masao Date: Fri, 24 Dec 2021 16:55:11 +0900 Subject: postgres_fdw: Allow postgres_fdw.application_name to include escape sequences. application_name that used when postgres_fdw establishes a connection to a foreign server can be specified in either or both a connection parameter of a server object and GUC postgres_fdw.application_name. This commit allows those parameters to include escape sequences that begins with % character. Then postgres_fdw replaces those escape sequences with status information. For example, %d and %u are replaced with user name and database name in local server, respectively. This feature enables us to add information more easily to track remote transactions or queries, into application_name of a remote connection.
