Hi, I created an table with composite type array as datatype for one column.
When I query that table I need the pg_typeof(column) as record[] instead of
composite_type[].
I tried creating a separate function and returning record[], but below error
is thrown,
ERROR: PL/pgSQL functions cannot return type record[]
Below is sample for my requirement.
pali=# create type address as (number bigint, city varchar);
CREATE TYPE
pali=# create table person(name varchar, addresses address[]);
CREATE TABLE
pali=# insert into person values ('Michael', array[(82, 'NYC'),(24,
'Dunkirk')]::address[]);
INSERT 0 1
pali=# select pg_typeof(addresses::record[]) from person ;
pg_typeof
-----------
address[]
Here I expect record[] instead of address[].
Thanks in advance.
record type is not real PostgreSQL's type. It is just PLpgSQL only type. You cannot use it outside PLpgSQL.
