Hello hackers, We know that pg_waldump can statistics size for every kind of records. When I use the feature I find it misses some size for XLOG_SWITCH records. When a user does a pg_wal_switch(), then postgres will discard the remaining size in the current wal segment, and the pg_waldump tool misses the discard size.
I think it will be better if pg_waldump can show the matter, so I make a patch which regards the discard size as a part of XLOG_SWITCH record, it works if we want to display the detail of wal records or the statistics, and patch attached. What's your opinion? Regards, Highgo Software (Canada/China/Pakistan) URL : www.highgo.ca EMAIL: mailto:movead(dot)li(at)highgo(dot)ca
