It seems rather overdesigned anyway, considering that there's been exactly zero field demand for a customizable banner. The only reason the idea even came up was that Peter proposed a switchable banner as a compromise between different desires. But I think we've pretty much got consensus that everyone is happy with reducing the help text to type help for help, so there's really no need for customizing. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
Re: [HACKERS] get rid of psql welcome message
This idea may be taking it to the extreme but I thought I'd throw it out there anyway as everyone seems to want something different. (well there seems to be three variants that if all were available would keep most people happy) This may be one way to please everyone. What if the actual welcome message can be defined in the .psqlrc ? Something along the lines of - WELCOME_MESSAGE=Welcome to VERS_PSQL - VERS_SERVER\nSSL_INFO (or similar with tags available that will allow predefined info to be inserted) I also see with this path that there could be a configure option to specify the default welcome text, I am thinking three options would keep most happy without adjustment in .psqlrc --default-welcome-message=[classic|short|oneline|custom string] custom string would match the above setting options - classic would be the default. This could also give the option in .psqlrc of having - WELCOME_MESSAGE=CLASSIC From there you can customise the setting to what you want and even across all machines in the office to match company policy (so to speak) setting default .psqlrc file for new users etc. Along that line maybe implement a way to have default welcome message settings per server? psql retrieves the welcome settings upon server connection. (as in psql requests it after connection - not returned with the initial connection request) This would be the default that is overridden by the local .psqlrc file. -- Shane Ambler pgSQL (at) Sheeky (dot) Biz Get Sheeky @ http://Sheeky.Biz -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

O.k. that makes sense. I have zero desire to take away from the work
that Peter did. However, I see less use of the .psqlrc and I find it
more likely that a shortened default banner would be beneficial. *shrug*
Maybe we should add an additional paragraph to the psql welcome message:
You can shorten or eliminate this welcome banner by modifying your .psqlrc
file and setting the WELCOME_MESSAGE to either terse or none. For more
information on the .psqlrc file and it's available options, please see the
postgresql documentation.
This would provide even more help for newbies, and encourage people to learn
about the .psqlrc file. :-)

I like that idea. Here is a minimal patch that allows you to put
\set WELCOME_MESSAGE none
or
\set WELCOME_MESSAGE terse
into .psqlrc. The latter keeps the version information but omits the
information about the backslash commands. I didn't change any of the message
wordings. Simon's argument that screenshots and HOWTOs would need to be
updated is not invalid.

The information presented in the welcome screen is to verbose, but is
still useful information. It is surely a cosmetic patch but there was
support for the idea.
My thoughts are to have the initial prompt look something like this:
--
psql 8.1.10 - Server version 8.2.7 (some features may not work)
Type: \h for SQL help, \? for psql help, \q to quit
SSL: On {cert info}
--
One of the things I have found is that the more information you provide
someone, the less likely they are to read it. (Every single class I have
taught has this problem).
I think the above presentation is less bulky, provides essential
nutrients and still gets the job done.

I think the information that you use \g or semicolon to launch a query is
surprisingly non-obvious to some users. One reason is that it doesn't always
work that way in the interactive terminals of other database systems. I
think that bit should be kept in the verbose version of the message.

Actually in thinking about this more... I almost thing the default
prompt should be:
-
psql version 8.2.7, server version 8.3.1 (some features may not work)
SSL: On {cert info}
Type help to get help (tab complete enabled)
-
So on the prompt they can do:
help Tab tab and it would give back:
help [sql | psql] (or something like that)
Then if they type:
help psql, they get back the current \?
If they type help sql they get back the current \h
If they don't know what they need, help is the shortest path to find
out. If they do know what they need, then we don't need everything else.

Does Win32 have tab completion? I am wondering if we should lose the

help [sql | psql]
in the header, again assuming we want to actually have 'help' so
something. I am afraid the phrase tab completion is too complex for
the type of people who need help. :-)

My idea is all about the 99% of people that don't use a .psqlrc. Should we not provide a simpler interface that provides succinct and need to know information just because we added a feature to .psqlrc? You missed my point entirely, which is that if we shorten the default banner help to ~1 line then this .psqlrc feature isn't going to get added, because it'd be useless. It's only useful given the premise that the default output will continue to be verbose. I'm not against shortening the banner.

If you do this, adding psql internal variables so a prompt could be built would be a nice way to go. For a default, perhaps nothing special at all to flag the connection as ssl? If it matters to someone, they can always set their prompt default to include this, set pgsslmode appropriately, or call ensure sslinfo is installed and use it. Is it worth promoting sslinfo into the core and adding a few new functions to expose at least the same information (cypher, etc)?
