Subject: Fix of separate pool for upstream connections (r4117).
X-Git-Tag: release-1.1.4~1
X-Git-Url: http://git.kaiwu.me/postgresql/log/contrib/postgres_fdw/static/%7B@url%7D?a=commitdiff_plain;h=afe2e3d082c5b6501d0107d86ecdfff36f458b85;p=nginx.git

Fix of separate pool for upstream connections (r4117).

Pool may not be created if connection was created but rejected in connect()
call.  Make sure to check if it is here before trying to destroy it.
