Subject: Ensure walsenders can be SIGTERMed while in non-walsender code
X-Git-Tag: REL9_1_2~86
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=5df22bba644d1c083118942292097ba2395fad15;p=postgresql

Ensure walsenders can be SIGTERMed while in non-walsender code

In oder to exit on SIGTERM when in non-walsender code,
such as do_pg_stop_backup(), we need to set the interrupt
variables that are used there, and not just the walsender
local ones.
