Just to clarify:

This patch will cause both executions of the example query to fail with the
"set-valued function..." error.

Also, the reason the "::varchar" one did not fail was because not cast
function was ever called but the "::varchar(30)" forced a function call and
thus prompted the error when the second record and resultant regexp_matches
expression was encountered.

Thanks!
