How to remove carriage returns and new lines in Postgresql?

Question

All,

I am stuck again trying to get my data in a format that I need it in. I have a text field that looks like this.

\"deangelo 001 deangelo

Answer 1

OP asked specifically about regexes since it would appear there's concern for a number of other characters as well as newlines, but for those just wanting strip out newlines, you don't even need to go to a regex. You can simply do:

select replace(field,E'\n','');

I think this is an SQL-standard behavior, so it should extend back to all but perhaps the very earliest versions of Postgres. The above tested fine for me in 9.4 and 9.2
