PGConf NYC 2023 Talks Wiki page

I have created the wiki page for PGConf NYC 2023 [1], and have linked one presentation/slides that I found a link to.

The slides were about 3.8 MB, and wiki wouldn't let me upload anything larger than 2MB, so I had to settle for the link. I think it's necessary to upload these files to the Postgres wiki, because the off-site links are prone to bit rot; e.g. the PG Conf NYC 2014 wiki page [2] contains links some of which seem to be dead.

I would really appreciate it if some attendees, or organizers can link or upload more talks to this wiki page.
