Hi!
Does PostgreSQL expose its hash function? I need a fast way to hash a
string to a short code using characters in the set [A-Za-z0-9_].
Is md5 good enough? :)
Probably not. He said fast.
You could use hashtext() which is Postgres's internal hash function.
There's some possibility it could change in future versions of Postgres
though.
