I imported a bunch of data using pgloader, and am now seeing that there's a bunch of whitespace (both spaces and tabs) inside of the fields. Is there a way to quickly update the fields to remove it from the beginning, the end, and the middle? I know there's TRIM, but that won't work for me...

As an added problem... I only want to remove double spaces and replace it with a single space, but there might be 5 or 6 spaces in a row, and I'd prefer not to have to rerun a replace query until they're all ok?

I was looking at regex_replace, but, I'm not sure how to make certain that it removes it from the middle of a string as well...

regex to match trailing whitespace, but not lines which are entirely whitespace (indent placeholders

I've been trying to construct a ruby regex which matches trailing spaces - but not indentation placeholders - so I can gsub them out. I had this /\b[\t ]+$/ and it was working a treat until I realised it only works when the line ends are [a-zA-Z]. :-( So I evolved it into this /(?!^[\t ]+)[\t ]+$/… >>> More
