And so, I find it really difficult to justify investing time in building up infrastructure to support it for my clients' work, because I need to be effective from day one.

Realistically that has absolutely nothing to do with PostgreSQL but whether or not some little third-party company or one or two individual developers have built something solid like Sequel Ace. That's really troubling for me to think about, but these CLI tools are insufficient for being productive.

This a great example to me as to why a business can't use a potentially superior product because some ecosystem feature is non-existent, or is hard to find.

That being said, I'm not too upset because modern MySQL seems perfectly fine, and still more widely used than PostgreSQL.
