Hi,
I have small problem with text array in union query.. see:
abil=> select 5 union select 5;
?column?
-------- 5
(1 row)
abil=> select 5 union select 6;
?column?
-------- 5 6
(2 rows)
abil=> select '{"aaa"}'::_text union select '{"aaa"}'::_text;
?column?
--------
{"aaa"}
(1 row)
abil=> select '{"aaa"}'::_text union select '{"bbb"}'::_text;
ERROR: Unable to identify an ordering operator '<' for type '_text' Use an explicit ordering operator or modify
thequery
abil=>
... hmm, any suggestion?
