seems like a bug, since PostgreSQL 15 - pgPedia - a PostgreSQL Encyclopedia does not mention anything about domain/cast changes.
the following code works on
PostgreSQL 15devel (Ubuntu 15~~devel~20220407.0430-1~713.git79b716c.pgdg20.04+1) on x86_64-pc-linux-gnu, compiled by gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0, 64-bit
---
create domain isodow as integer check(value between 1 and 7);
create function testcast(in a timestamptz ,out isodow)
as $$ select extract(dow from a ) $$ language sql;
CREATE CAST (timestamptz AS isodow) WITH FUNCTION testcast(timestamptz) AS ASSIGNMENT;
----
then execute it:
select '2022-04-23 19:00:01 +5:30'::timestamptz::isodow;
return 6
---
however when i run it PostgreSQL 14.2 (Ubuntu 14.2-1.pgdg20.04+1+b1) on x86_64-pc-linux-gnu, compiled by gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0, 64-bit
yield the following error:
ERROR: 42846: cannot cast type timestamp with time zone to isodow
LINE 1: select '2022-04-23 19:00:01 +5:30'::timestamptz::isodow;
^
