Bug in sub-query

Hi Team,

I have observed one bug in postgres 

create table admin.emp (sno integer,name varchar(100),location_id_location integer);

create table admin.emp_dimension (dim_id integer,employee_name varchar(100),location_id integer);

insert into admin.emp select 1,'vara',108;

insert into admin.emp select 2,'saasthra',108;

insert into admin.emp_dimension select 1,'varaprasad',108;

insert into admin.emp_dimension select 2,'saasthra peddireddy',108;

--query 1:

select * from admin.emp_dimension where location_id_location=108;

--Note: it failed because "ERROR:  column "location_id_location" does not exist

--query 2:

select * from admin.emp where location_id_location=108

and sno in (select dim_id from admin.emp_dimension where location_id_location=108)

--Note2: it returned two records and no error given. 

--But if you observe above query 2; the sub-query is not correct. In sub-query; location_id_location is not present in table admin.emp_dimension. But same sub-query failed in query 1.

select version()--

"PostgreSQL 16.8 on x86_64-pc-linux-gnu, compiled by x86_64-pc-linux-gnu-gcc (GCC) 10.5.0, 64-bit"

The issue is present in other versions as well. Please check and fix it.
