Hi hackers~
I find the specification of wal_compression in our docs a little bit confusing
for it 'compress full page images when FPW is on or during a base backup',
which was true before v17. Since v17, we will also use full page images for
creating index or table rewrites through bulk write, so it is inaccurate.
Should we change the doc a little bit: 'compress full page images written
to WAL, **like** when FPW is on, or during a base backup', if we may use
FPI in other places in the future?
