I was using pgAdmin to create my tables and while I was not using reserved words, the generated table had a quote in the name and a couple of columns had quotes in them. Here is an example of the generated SQL.
CREATE TABLE public."Test"
(
id serial NOT NULL,
data text NOT NULL,
updater character varying(50) NOT NULL,
"updateDt" time with time zone NOT NULL,
CONSTRAINT test_pk PRIMARY KEY (id)
)
TABLESPACE pg_default;
ALTER TABLE public."Test"
OWNER to svc_newnews_app;
All of these quotes were inserted at "random". I just needed to drop and re-create the table again without the quotes.
Tested on pgAdmin 4.26
