Bug reference: 7520

PostgreSQL version: 9.1.4
Operating system: Gentoo
Description: =
I am using regexp_matches in a function like this
create or replace function test (v_string in text)
returns varchar as $$
declare
i_strings text[];
i_string text[];
i_strings :=3D
regexp_matches(v_string,E'[a-zA-Z0-9:\\s\\-\\.#%]*:[A-Za-z0-9\\s\\-\\.#%]+'=
,'g');
The I use the results =
foreach i_string slice 1 in array i_strings
loop
raise notice 'row =3D %',i_string;
end loop;
when I run the function like this
select test('1:Warehouse1;2:Warehouse2;');
postgresql complains:
ERROR: query "SELECT
regexp_matches(v_string,E'[a-zA-Z0-9:\\s\\-\\.#%]*:[A-Za-z0-9\\s\\-\\.#%]+'=
,'g')"
returned more than one row
Off course I am expecting more than one row!
If I run:
select
regexp_matches('1:Warehouse1;2:Warehouse2;',E'[a-zA-Z0-9:\\s\\-\\.#%]*:[A-Z=
a-z0-9\\s\\-\\.#%]+','g');
regexp_matches =
----------------
{1:Warehouse1}
{2:Warehouse2}
(2 rows)
