Hi,
Here is a proposal to implement HIDDEN columns feature in PostgreSQL.
The user defined columns are always visible in the PostgreSQL. If user wants to hide some column(s) from a SELECT * returned values then the hidden columns feature is useful. Hidden column can always be used and returned by explicitly referring it in the query.
The behaviour of SELECT * is well defined and consistent across many databases, so I don't like changing the behaviour of it.
I would be in favour of a different symbol which expands to a more selective column set. Perhaps by default it picks up short textish columns; skip bytea or long text fields for example but can be adjusted with HIDDEN. Perhaps "SELECT +"?
