I have an application where I drop, recreate, reload, and recreate

One of the annoying things in plpgsql is logical expression
evaluation.
In most (all??) languages I know, logical expression like:

will stop evaluating when the A expression will be evaluated as a
TRUE.
So the B will be not checked.
