seems like a good idea to me :-)
If you propose a patch with a function that returns a setof text, I am
sure it would get some attention. Though I think that you should
remove the mention of the 20th anniversary.
Thank you for the feedbacks.
Good idea. I will write a function. The most basic would be:
CREATE OR REPLACE FUNCTION pg_logo()
RETURNS SETOF TEXT
AS $$
BEGIN
RETURN QUERY SELECT ' ____ ______ ___ '::TEXT;
RETURN QUERY SELECT ' / )/ \/ \ '::TEXT;
RETURN QUERY SELECT '( / __ _\ )'::TEXT;
RETURN QUERY SELECT ' \ (/ o) ( o) )'::TEXT;
RETURN QUERY SELECT ' \_ (_ ) \ ) _/ '::TEXT;
RETURN QUERY SELECT ' \ /\_/ \)/ '::TEXT;
RETURN QUERY SELECT ' \/ <//| |\\> '::TEXT;
RETURN QUERY SELECT ' _| | '::TEXT;
RETURN QUERY SELECT ' \|_/ '::TEXT;
RETURN;
END;
$$ LANGUAGE plpgsql;
charles@charles.[local]=# select pg_logo();
pg_logo
-----------------------
____ ______ ___
/ )/ \/ \
( / __ _\ )
\ (/ o) ( o) )
\_ (_ ) \ ) _/
\ /\_/ \)/
\/ <//| |\\>
_| |
\|_/
(9 rows)
But I'd like to add arguments so that it is possible to add a frame and
a text as TEXT[]. Additional arguments for the text would be the
position (bottom or right) and the alignments (top, bottom, left, right,
center). All arguments should have default values so that calling the
function without arguments delivers the logo as in the above basic function.
A question to the naming. I find pg_logo() also a good name, but is the
prefix pg_* not reserved for system functions? Of course I could use the
name I want, but was wondering if there is a policy or a best practice
in this area.
And what schema would be appropriate? I could also create the function
without defining a schema and let users decide where they want to put it.
An alternative for the name could be logo(), in analogy to version().
Bye
Charles
