Subject: postgresql plugin: If a query fails, try to reconnect immediately.
X-Git-Tag: collectd-5.3.0~44^2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=e14c0448fb1afe92cba0716b9f6bd8e1805d16fe;p=collectd.git

postgresql plugin: If a query fails, try to reconnect immediately.

Else, we would unnecessarily skip one iteration even when being able to
reconnect right away.
