Error message when saving page

[lordcycy]

I get this error message appearing in a red box when saving a page:

UPDATE "pagesVector" SET title = $1, description = $2, tokens = (setweight(to_tsvector('simple', $3), 'A') || setweight(to_tsvector('simple', $4), 'B') || setweight(to_tsvector('simple', $5), 'C')) WHERE path = $6 AND locale = $7 - relation "pagesVector" does not exist

but the page saves correctly.

What is causing this? Can it lead to issues long term?

I'm using postgreSQL
