Update: PostgreSQL 18.6

This updates to the latest release of PostgreSQL (the 18.5 release was
skipped). Release announcement at
https://www.postgresql.org/about/news/postgresql-186-1711-1615-1519-1424-and-19-beta-3-released-3365/

A whole bunch of security issues, so if someone could take care of
-stable after I commit, I would appreciate it.

Tested on amd64. I plan on committing in a couple days unless I hear
objections.

Best,
Jeremy
