Tom Lane cf9b0fea5f Implement regexp_match(), a simplified alternative to regexp_matches(). ... regexp_match() is like regexp_matches(), but it disallows the 'g' flag and in consequence does not need to return a set. Instead, it returns a simple text array value, or NULL if there's no match. Previously people usually got that behavior with a sub-select, but this way is considerably more efficient. Documentation adjusted so that regexp_match() is presented first and then regexp_matches() is introduced as a more complicated version. This is a bit historically revisionist but seems pedagogically better. Still TODO: extend contrib/citext to support this function.
