I use it as the only database in most of the projects I've work at my company, using Ohm [1] as our ORM. Usually we don't have use cases with ad hoc queries like `name LIKE '%Smith'`, so it serves our purposes very well. When we need something like that, we integrate with something like Elasticsearch.
SSL connection error
Unable to make a secure connection to the server. This may be a problem with the server, or it may be requiring a client authentication certificate that you don't have.
It's not a certificate problem, I think somebody's misconfigured the server. It's listening on port 443, but not actually responding appropriately to TLS traffic.
