From 94c49d53402240ad7ddbcae9049ff2840a54b9c6 Mon Sep 17 00:00:00 2001 From: Fujii Masao Date: Fri, 18 Feb 2022 11:38:12 +0900 Subject: postgres_fdw: Make postgres_fdw.application_name support more escape sequences. Commit 6e0cb3dec1 allowed postgres_fdw.application_name to include escape sequences %a (application name), %d (database name), %u (user name) and %p (pid). In addition to them, this commit makes it support the escape sequences for session ID (%c) and cluster name (%C). These are helpful to investigate where each remote transactions came from.
