Native postgresql driver

[torhve]

There has recently been released a native lua cosocket driver for postgres here:
https://github.com/azurewang/lua-resty-postgres

I did some simple benchmarking ("SELECT 1") and the native driver came out roughly three times as fast for this simple test. I have not done thorough benchmarking.

But maybe the biggest favorable is getting error messages back to the programmer.

Would you consider adding support for this driver?
What about other drivers, lua-resty-mysql, etc, easily doable to abstract out the postgresl-specific parts ?

Awesome, I was aware of this but hadn't had a chance to benchmark it yet. I'll look into implementing it shortly. Being able to have error messages would be very helpful.

I'm not against adding other drivers (specifically mysql). It's not a high priority for me personally because Postgres is what I use. If other people show some interest then I don't mind adding support.

Alright. If for no other reason, the TechEmpower benchmark uses MySQL. And I'd love to see lapis included in that benchmark.
