Re: R: Fault when return strings over 256 characters in PLpgSQL

Thanks - we have realised that it is a 'feature' of the pgAdmin III query
window (if the data is viewed directly then it is correct): and is listed
in the pgadmin FAQS as 'query data is truncated'. Its just a pity they
don't use something more recognisable such as ... or (...)

Subject: R: [BUGS] Fault when return strings over 256 characters in PLpgSQL

It could be a pgAdmin III presentation fault.
I'm using PostgreSQL 8.0.0 on Windows 2k and I've got the same problem
but only when inquiring via pgAdmin, using psql from command line all
goes ok. I think that the resulting string are correct, that's why the
function "position(\'.\' in userName);" doesn't find the dot.

I'm skeptical: there is nothing special about 256 characters as far as
the varchar implementation is concerned, nor is the string ' (.' of any
significance.

Running your function (albeit on Linux) yields:

neilc=# select testconverttousername();

testconverttousername

i.e. what one would expect.
