I have a table that contains message_content. It looks like this:
message_content | WFUS54 ABNT 080344rr
| TORLCHrr
| TXC245-361-080415-r
How would I extract only the 2nd line of that output(TORLCH)? I've tried to shorten the output to a certain number of characters but that ultimately doesn't provide what I want. I've also tried removing carriage returns and new lines. I am outputting my results to a CSV I could manipulate with Python, but was wondering if there's a way to do it in the query first.
Based on other examples, it seems like I could use a regular expression to maybe do this? Not sure where to start with learning that though.

you can split the line into an array, then take the second element:
(string_to_array(message_content, e'rr'))[2]
