I’ve been instructed “not to bother with LIKE” and use ~ instead. What is wrong with LIKE and how is ~ different?
Does ~ have a name in this context or do people say “use the tilde operator”?
~is the regular expression operator, and has the capabilities implied by that. You can specify a full range of regular expression wildcards and quantifiers; see the documentation for details. It is certainly more powerful thanLIKE, and should be used when that power is needed, but they serve different purposes.
