Change xl_hash_vacuum_one_page.ntuples from int to uint16.
This will create two bytes of padding space in xl_hash_vacuum_one_page whichcan be used for future patches. This makes the datatype ofxl_hash_vacuum_one_page.ntuples same as gistxlogDelete.ntodelete which isadvisable as both are used for the same purpose.Author: Bertrand DrouvotReviewed-by: Nathan BossartDiscussion:https://postgr.es/m/b0e20c40-cb7a-fc1c-c607-2a78dac5021e@gmail.com
