Hello, all
Could you give me your opinions on whether the SHOW command should display the effective value or the specified value
forhuge_pages? During the review of "Supporting huge_pages on Windows", which is now shifted to CommitFest 2017-3,
Magnusgave me a comment that the huge_page variable should retain the value "try" when the huge page is not available
onthe machine and the server falls back to huge_page=off. The Linux version does so.
I don't have a strong opinion on that, but I think a bit that it would be better to reflect the effective setting, i.e.
SHOWdisplays huge_pages as off, not try. Otherwise, the user cannot know whether the huge page setting is effective.
One parameter that behaves similarly is wal_buffers. When wal_buffers is set to -1 (default), "SHOW wal_buffers"
displaysthe actual size, not -1. But I didn't find any other parameters like this.
