Order of operations in postgreSQL.

Just a few notes on this issue:

PSQL:

Appears to be applying the filter to all the columns in the table after the join.

TSQL:

Tried to duplicate this behavior and got these results.

select t1.id as t1id,

       cast(cast(t1.test_value as varchar(max)) as datetime) as tms

from table1 t1

    join table2 t2

        on t1.id = t2.id

where cast(cast(t1.test_value as varchar(max)) as datetime) > '2023-05-27'

These statements work as expected in SQL Server.

Let me know if you have any questions.
