[libpostgresql-jdbc-java] 01/06: Deep inside the driver's underlying IO code there is a method to skip over incoming data and discard it. It returns the length of data actually skipped which may differ from the requested skip size. It was incorrectly calculating the total length skipped when it had some data buffered, but also needed to skip over some data it had yet to read. This bug does not affect any existing code because all current callers of skip ensure that enough data is buffered, so the skip can always be satisfied from the internal buffer alone.
