While doing some research for a question, I realized that
RULE is a PostgreSQL extension and not part of the SQL standard.
However there doesn't appear to be a tag for RULES on this site, there are a number on Stack Overflow but rules for example, has the following description:
This tag is very broad, try being more specific by using tags relevant to your problem. Examples are "rule-engine" for rules engines, "url-rewriting"/"mod-rewrite" for rewrite rules or "form-validation" for validation rules. See the full wiki article for a more complete list.
Can we have a
postgresql-rule tag for questions about
RULES, or this overly specific?
