Self-Alias not found (subquery using alias of its outer query)

CREATE TABLE my_table (id text NOT NULL PRIMARY KEY, name text NOT NULL, parent_id text);
CREATE INDEX my_table_idx_name ON my_table (name);
CREATE INDEX my_table_idx_id_parent_id ON my_table (id,parent_id);

SELECT * FROM my_table as t1 WHERE t1.name = 'test';
SELECT * FROM my_table as t1 WHERE t1.name = 'test' AND NOT EXISTS (SELECT * FROM my_table as t2 WHERE t2.parent_id = t1.id);

Alias 't1' not found

🐜 This seems to be an execution error, which means that your request syntax seems okay,
but the resulting statement cannot be executed → Probably not a pg-mem error.

*️⃣ Reconsituted failed SQL statement: SELECT *  FROM "my_table" AS "t1"  WHERE (("t1"."name" = ('test')) AND (NOT ("exists"((SELECT *  FROM "my_table" AS "t2"  WHERE ("t2"."parent_id" = "t1"."id") )))))

Just popping in to +1 this. It’s impacting my NestJS project as well. As AustinGil said though, take your time. You are doing an amazing job with this library and I am very grateful for all your effort. ^_^

I should’ve searched existing tickets before submitting mine. Seems test coverage is already done in the new branch, so that’s promising. Thanks!
