Log Message:
repmgr: updated to 5.0.0

repmgr 5.0 is a major release.
* Configuration file parsing has been made stricter
* Some "repmgr daemon ..." commands renamed
* Some deprecated command line options removed
* Support for PostgreSQL 12 added.
* The repmgr configuration file is now parsed using flex, meaning it will be \ 
parsed in the same way as PostgreSQL parses its own configuration files.
* repmgr standby clone: checks for availability of the repmgr extension on the \ 
upstream node have been improved and error messages improved.
* When executing repmgr remotely, if the repmgr log level was explicitly \ 
provided (with -L/--log-level), that log level will be passed to the remote \ 
repmgr.
* Bug fixes
