As I said, that's the return value of DatabaseMetaData.getDatabaseProductVersion()
So apparently there *is* some parsing going on.
PgDatabaseMetaData.getDatabaseProductVersion() calls connection.getDBVersionNumber();

PgConnection.getDBVersionNumber() calls queryExecutor.getServerVersion();

The receiveParameterStatus() of QueryExecutorImpl calls setServerVersion(value) of QueryExecutorBase:

There is no parsing going on.
In my Ubuntu
getDatabaseProductVersion() returns "10.2 (Ubuntu 10.2-1.pgdg16.04+1)".
