Solution proposal for TODO item "Clients: sequences"

That would be something good for 8.1 so I will keep your email.

This has been saved for the 8.1 release:

Dear People,

Hereby a proposal for the TODO item "Clients: Have psql show current values
for a sequences".
I have added a new slash command to psql client "\sq" for showing the last
values of the
existing sequences in the public schema. The code is only tested on rh9.

The new files are sequence_info.c and sequence_info.h I would like
to hear your comments. (Be gentle this is my first)

The sources can be downloaded from http://www.truesoftware.net/psql/

It would be nice to add the current sequence value to \ds, but the
existing psql query would have to be overhauled to do that. Right now
the same query does all the work for most \d commands.

So what would be your suggestion in order to add this functionality?

TIP 9: the planner will ignore your desire to choose an index scan if your
joining column's datatypes do not match

I would suggest adding it to \ds or create a \ds+ so that it is in
common with the rest of the commands.
