Oh my, I've been obfuscating. Again...
While having a couple of beers as mental lubricants in the
LAP (Local Area Pub), it came to my mind that just doing a
create aggregate test_agg_1 (
basetype = text,
stype1 = text,
sfunc1 = textcat,
initcond1 = '');
and then selecting like
select test_agg_1(textvar || ' ') from testtable;
perfectly suites my needs. Sorry for the fuzz!
Still I'm somewhat curious as to why my first
approach didn't work...
Greetings
