... or more likely, put the SQL file in a saner place. Dropping random
files into a program directory can only lead to trouble. You should
treat such directories as read-only unless you know exactly what you
are doing.
It seems likely to me that this failure stems from PG being installed
with permissions settings that prevent it from reading/modifying its own
executables, which is good solid security practice.
(If the tutorial actually told you to do that, the tutorial's author
is utterly clueless.)
