This function takes in input a WAL segment name and returns a tuple made of the segment sequence number (dependent on the WAL segment size of the cluster) and its timeline, as of a thin SQL wrapper around the existing XLogFromFileName(). This function has multiple usages, like being able to compile a LSN from a file name and an offset, or finding the timeline of a segment without having to do to some maths based on the first eight characters of the segment. Bump catalog version.
