Isn't there an adapter from mysql-to-postgres which would essentially mimic all the quirks in mysql onto an actual postgres?

I believe this is what Janus (NEXTGRES) does.

To clarify, the wire protocol is the easy part, the semantic differences how each database does things is a whole other can of worms. Such emulation will never be 100%, quirks and all.
