Обсуждение: Can't createlang plpgsql

Hello

I can't get pl/pgsql to install  using creatlang. I've listed what I did
and the messages I received.

I'm running 7.1.3 configured as follows:

./configure  --enable-multibyte=UNICODE --enable-unicode-conversion
--with-perl

The distro is  Redhat 7.1.

Thanks.

The error message you quote is not from 7.1's createlang, but 7.0
or before.  Perhaps you have a version mixup?

In any case, creating a PL language is a two-step process: install a
function and then define the language.  Evidently only the first of
these steps has gotten done.  Try dropping the function by hand and
then trying again.
