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?
