I suppose you work on Windows. The widget we use on Windows truncates
silently all strings to 512 characters. It means we need to fix this
(just as we did for the table properties dialog which suffered the same
issue).

To be complete, you have to know that even PostgreSQL truncates the
query in the pg_stat_activity stats catalog. By default to 1024
characters. So if your queries are longer than that, there's nothing we
can do.

Working on a fix right now.
