[erlang-questions] Of regexes and REs, and other irritating things...

Thanks everyone. It's a small temporary app on a closed network with
trusted clients. If you notice I'm not even fully protecting against SQL
injection; no octals or whatnot are checked ... it's literally just for a
few characters which people may type in (like O'Grady).
Didn't know the internals of the MySQL protocol - I've just been using
emysql and it seems to work fairly well. I've not done much postgres, but
while it's always had a good reputation it never seemed to be quite as
.... dynamic ... as the MySQL development process. I've been using MySQL,
well, forever but I'm open to exploring postgres again after this project
Which postgres clients (erlang) are considered solid and what's the
consensus on their clustering compared to Galera/Percona?
