Command line tools? In XXI century? No way! Yes way!

So, you just installed your PostgreSQL, and you have no idea how to use it – there is no icon in the menu of your OS, so how can you use it? Well, with the dreadful command line.

Of course – some people will never get used to textual programs. They need a GUI. That's fine. Not understandable for me, but who am I to judge.

Waiting for 8.5 – better wrapped output in psql

On 22nd of November Tom Lane committed patch by Roger Leigh which fixes my pet peeve:

Log Message:
-----------
Improve psql's tabular display of wrapped-around data by inserting markers
in the formerly-always-blank columns just to left and right of the data.
Different marking is used for a line break caused by a newline in the data
than for a straight wraparound.  A newline break is signaled by a "+" in the
right margin column in ASCII mode, or a carriage return arrow in UNICODE mode.
Wraparound is signaled by a dot in the right margin as well as the following
left margin in ASCII mode, or an ellipsis symbol in the same places in UNICODE
mode.  "\pset linestyle old-ascii" is added to make the previous behavior
available if anyone really wants it.
 
In passing, this commit also cleans up a few regression test files that
had unintended spacing differences from the current actual output.
