Could you post a small but complete program that exhibits the
problem? Without seeing your code we can only guess what might be
wrong. Also, please post the complete, exact text of the error
message (copied and pasted, not typed manually).
I suspect the real error is something like the following:
DBD::Pg::st execute failed: execute called with an unbound placeholder at ./foo line 14.
If that's the case, then you might have called $sth->execute() with
no arguments when you should have called it with arguments, e.g.,
$sth->execute($variable). But that's just a guess; without seeing
your code we can't be sure.
