Hiya,

Bit of a basic question.

I has asked about a year ago about how to deal with data from a 
subselect, and was regaled with tales of the wondrous new 
functionality of the release known as "8".

Okay. Got that version. (Better late than never.)

Now I need to (sub) select an arbitrary number of string values and 
return them as a single string value. Can't simply concatenate, 'cuz 
of the arbitrariness.

Where is the documentation for what I need? I'm just not finding it 
on the site or through Google. Is it under "cast" or something else?

And I'm getting some errors on the site in general. Searching for 
"subselect string" gives me this one link, which gives me a broken page...
<http://techdocs.postgresql.org/guides/SetReturningFunctions>

Thanks for any pointers...

-Ben
