Oh wow, thanks for noticing that. I had already rewritten the commit
message to some extent, but "master" had remained. Now I pushed the
patch to branches 14+, having replaced it as you suggested.
(This reminds me that I used to have a notification set in the
2ndQuadrant Mattermost instance so that I could LART anybody who used
the words 'master' or 'slave' in the chats there).

Oh, okay. The initial size is just there to avoid having to grow the
hash table, but using the same constant that we use for the filemap hash
table seems good enough ... it shouldn't make much of a difference in
practice.
