Hi, thank you for fast answer.
Maybe i wasn't too accurate in terms, because I newbie, but:
We can get information about xlog, using big amout of support function
(pg_current_xlog_location(), pg_current_xlog_insert_location(),
pg_xlogfile_name_offset(), pg_xlogfile_name(),
pg_last_xlog_receive_location(), pg_last_xlog_replay_location(), ...
etc) they helps to get get useful information about xlog files and its
content. So, this patch extends this amount of functions.
This function is mostly for debugging purposes.
