Picking out the relevant error:

2023-05-08T11:50:21.600015+03:00 ERROR PostgreSQL Database error 42703: column "authorid" referenced in foreign key constraint does not exist

The query is: ALTER TABLE "pages" ADD FOREIGN KEY(authorId) REFERENCES "users"(authorId) ON UPDATE NO ACTION ON DELETE NO ACTION

Instead it should be: ALTER TABLE "pages" ADD FOREIGN KEY("authorId") REFERENCES "users"("authorId") ON UPDATE NO ACTION ON DELETE NO ACTION

(That will cause other errors to pop up, but that's just an artefact of the simplistic repro schema.)

Were you able to figure out a way around this @Artanicus? I'm struggling with the exact same issue, sqlite3 -> postgres.

EDIT: I found this open PR which fixes the issue #1531

pgloader version: 3.6.7~devel (I'm not sure why it says this, I am using Docker tag 3.6.9, and I've also tried latest.
