Hi Filip,
The example occurs when I pass the parameter via
PEARDB . I made the mistake of setting the int4 type
for a variable that could assume int8 values. So, when
I passed, for example, a five digit integer, it made
the coercion and returned no error, and the function
had ran with the wrong value.
But, when I've changed this (setting the variable type
to int8), it worked as I expected.
Thank you!
