The pgbench expression grammar mimics SQL expression grammar,
on integers, floats, booleans & NULL.

I'm unsure about some special cases in psql (`shell command`,
'text' "identifier"). They can be forbidden on a new commande (\let),
but what happens on "\if ..." which I am afraid allows them is unclear.
