Re: pgbench more operators & functions

Hi,

The patch has correct precedence now.

Further minor comments:

1. About documentation, I think it will be good idea to arrange the
operators
table with the precedence and add a line at top: "In decreasing order of
precedence".

2. You may want to remove the comment:
+           /* should it do a lazy evaluation of the branch? */
