Steven Hawkins updated TEIID-2453:
----------------------------------

        Summary: Add a string_agg or similarly named aggregate for creating a delimited concat  (was: Allow textagg to perform simple delimited concat)
    Description: Similar to the pg string_agg (which supports blob/clob) delimited concat, we should offer a built-in aggregate.  (was: If the text line ending is configurable, then textagg can be used to mimic mysql groupconcat functionality.)

Changing from the original issue, which was a modification to text_agg as the text_agg intent is really tailored toward csv construction and would be unnecessarily complicated by this change.
