pgbench: Add a real expression syntax to \set

Enterprise / PostgreSQL - Robert Haas [postgresql.org] - 2 March 2015 13:21 UTC

Previously, you could do \set variable operand1 operator operand2, but nothing more complicated. Now, you can \set variable expression, which makes it much simpler to do multi-step calculations here. This also adds support for the modulo operator (%), with the same semantics as in C.
