PLPGSQL Installation

Hi,

I have some problems running the procedural extension PLPGSQL.

I install PLPGSQL into my database using the "createlang" command and
everything seems to be OK, when I check it using "createlang -l".

Then I create a simple function, cut'n'pasted from the manual, and insert
it into the database. This also seems to be working quite fine.

But when I try to run this (or any other) PLPGSQL function, i get this
error message: "plpgsql: ERROR during compile of xxx near line 1".

Is there anything else I need to do (apart from running "createlang") in
order to use PLPGSQL or am I doing something wrong here?

Any kind of help is highly appreciated.

Thanks very much,
Jan Rudovsky
