Re: proposal: condition blocks in psql

I implemented \foreach  five years ago, and this is not simple to implement statement - so don't propose it. I wouldn't to inject full scripting language to psql. Then it is better to use bash, perl, python.

But well designed conditional statements needs only few lines for implementation, and be good enough for almost all tasks what I need to do in psql. More the working with versions needs a different operation than comparing strings or comparing numbers, and can be nice if this functionality is available with some user friendly syntax.
