Re: pgsql: meson: docs: Add {html,man} targets, rename install-doc-*

Commits look fine to me, but I hate the new target names... Luckily,
I just use plain ninja, so I don't interact with that.

My only comment is that you could reverse the logic and save yourself an
indentation.

- if len(targets_info_byname[name]) > 1:
+ if len(targets_info_byname[name]) <= 1:
+     continue

But whatever you want.
