You can implement this by overwriting a line. Use \r to go back to the beginning of the line without writing \n to the terminal.

Write \n when you're done to advance the line.

Use echo -ne to:

• not print \n and
• to recognize escape sequences like \r

Let's define a variable containing leading, trailing, and intermediate whitespace:

FOO=' test test test '
echo -e "FOO='${FOO}'"
# > FOO=' test test test '
echo -e "length(FOO)==${#FOO}"
# > length(FOO)==16

What / Why

Deploy key is a SSH key set in your repo to grant client read-only (as well as r/w, if you want) access to your repo.

As the name says, its primary function is to be used in the deploy process, where only read access is needed. Therefore keep the repo safe from the attack, in case the server side is fallen.

How to

1. Generate a ssh key

PostgreSQL has Foreign Data Wrappers. A very powerful feature. Greenplum 
has External Tables. Also a very powerful feature. In fact, it's pretty 
much the same feature. As we catch up with PostgreSQL, we need to figure 
out what we're going to do about that. In the long run, we clearly don't 
want to maintain two features that do the same thing, but with different 
syntax and different set of wrappers/plugins.
