Hello all
A simplification of the problem I found:
Here is a function (taken from the postgres documentation)
```
CREATE FUNCTION add(integer, integer) RETURNS integer
AS 'select $1 + $2;'
LANGUAGE SQL
IMMUTABLE
RETURNS NULL ON NULL INPUT;
```
"Accidentally" did the following:
```
SELECT add(3,4) END;
```
On postgres 14 and over+ there is no problem:
```
end
-----
7
(1 row)
```
On Postgres 13 and under:
```
ERROR: syntax error at or near "END"
LINE 1: SELECT add(3,4) END;
```
On the list of reserved words, END is marked as reserved.
https://www.postgresql.org/docs/current/sql-keywords-appendix.html
Since postgres 14+ is not reserved and can be used, for example as a column
name.
Unless I am mistaken that shouldn't happen.
Made a small CI test with the code above: (link will be unavailable when gihub
removes the workflow)
Fails as expected as `end` is a reserved word (pg13)

But on the other test runs it has no problem (pg17)
