Hi, The current documentation of pgbench’s \aset command states:
“If a query returns no row, no assignment is made and the variable
can be tested for existence to detect this.”
However, this is inaccurate, since variable existence check (like \if :{?var})
is not yet supported, although such a feature was proposed in [1] and discussed
again in [2], where \aset itself was introduced.
Therefore, I’ve attached a patch to remove this part from the documentation.
