Thanks for working on this. I had just a quick look at it, but I hope I'll have
time to post a proper review. In the meantime I'm wondering what am I doing
wrong here (I see a similar example in your first message)?

```
-- test.sql
\if random(0, 99) < 85
\set test 1
\else
\set test 2
\endif
select :test;
```

```
$ pgbench -s 10 -f test.sql
test.sql:1: unexpected character (<) in command "if"
\if random(0, 99) < 85
^ error found here
```

I'm using `pgbench-if-4.patch`, and everything is fine for simple
conditions like `\if 1`.
