Make PostgresNode version aware
A new PostgresVersion object type is created and this is used in
PostgresNode using the output of `pg_config --version` and the result
stored in the PostgresNode object. This object can be compared to other
PostgresVersion objects, or to a number or string.
PostgresNode is currently believed to be compatible with versions down
to release 12, so PostgresNode will issue a warning if used with a
version prior to that.
No attempt has been made to deal with incompatibilities in older
versions - that remains work to be undertaken in a subsequent
development cycle.
Based on code from Mark Dilger and Jehan-Guillaume de Rorthais.
