brew services restart postgres is successful, there may be an error occurring, view your log, which for me with homebrew’s install was
tail -n 50 /usr/local/var/log/postgres.log. If you see something like the following, you may need to switch a package version back to something older:
dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.64.dylib
Referenced from: /usr/local/opt/postgresql/bin/postgres
Reason: image not found
For me, after an OS update, the icu4c package had been changed, so I needed to switch it back, using
brew switch icu4c 64.2

The solution for this was to run:
brew upgrade chromedriver (this used to be
brew cask upgrade chromedriver). You may possibly need to update your chrome browser. The comments on this issue/repo were very helpful: https://github.com/elixir-wallaby/wallaby/issues/468.
Generally, it would seem it is a good idea to keep your chromedriver in sync with your updates to Chrome (run
brew upgrade chromedriver when you update Chrome.
Issue: Getting the (current or otherwise) date for a specific timezone can be involve some trickiness.
Example: I want to show the current date in New York, even though I reside in Austin, TX. If it is 12/11/2020 11:39 PM CT:
- The display for NY data should show 12/12/2020
- A display for Austin, TX would show 12/11/20202
NOTE: When dealing with DateTimes to save to a database, leaving the microseconds on can cause issues. I’m surprised the DateTime result doesn’t default to the more compatible format (TBD on whether from Elixir or Timex). See https://github.com/riverrun/phauxth-example/issues/10
