That getLastError() approach has another big plus. Currently there is no way to get error message in t3lib_db. There is a method sql_error but this is not truly the same and it does not provide error code for possible analysis and recovery.

And actually, wouldn't TYPO3_DB->sql_error() return this error message if connection fails?

I did not mean that I nicely formatted html should be returned, I just expanded the idea of showing this error in FE :) Sure, t3lib_db must not care about html formatting, etc. I thought about function in t3lib_div (it becomes a big mess really!) that can format error messages like this in a standard way and optionally (by default) exit.
