Subject: Avoid protocol breakage when pooler fails to open connection to one or more
X-Git-Tag: XL_10_R1BETA1~668
X-Git-Url: http://git.postgresql.org/gitweb/static/gitweb.js?a=commitdiff_plain;h=eebf6f3a2d221bb8165d3fca111e19421cbaf3c1;p=postgres-xl.git

Avoid protocol breakage when pooler fails to open connection to one or more
nodes.

While the pooler sends both fds as well pids, the client was bailing out early
if it can't find required number of fds, thus causing protocol breakdown
