A.62. Release 3.4.18

A.62.1. Bug fixes

• Prevent pcp_recovery_node from recovering "unused" status node. (Tatsuo Ishii)

  This allowed to try to recovery a node without configuration data, which leads to variety of problems.

  See [pgpool-general: 5963] for more details.

  Also I fixed pgpool_recovery function so that it quotes an empty string argument with double quotes.
