 As I said, that's the return value of DatabaseMetaData.

getDatabaseProductVersion()

So apparently there *is* some parsing going on.


​
PgDatabaseMetaData.getDatabaseProductVersion() calls connection.getDBVersionNumber(); 
https://github.com/pgjdbc/pgjdbc/blob/45c32bc6af2e140ff86dabd718344c74fc244394/pgjdbc/src/main/java/org/postgresql/jdbc/PgDatabaseMetaData.java#L150

PgConnection.getDBVersionNumber() calls queryExecutor.getServerVersion(); 
https://github.com/pgjdbc/pgjdbc/blob/45c32bc6af2e140ff86dabd718344c74fc244394/pgjdbc/src/main/java/org/postgresql/jdbc/PgConnection.java#L892
​
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)".
