postgres first line comment shows no results

[jameshowison]

It seems that having a -- comment on the first line of a cell causes no result to be displayed by postgres. e.g.,

-- new query
SELECT *
FROM pg_catalog.pg_tables;

Shows no result,. but

SELECT *
FROM pg_catalog.pg_tables;
-- new query

Shows results.

This is easy to fix! I'll open a PR... There's so much stuff I want to rewrite in this software though! 😅
