CONNECT BY is Oracle's way of implementing recursive queries. We had a patch for that for years, but it was rejected over and over on various grounds, one of which was that it was not the standard's spelling of the feature. We only got recursive queries when somebody was willing to bite the bullet and write it in WITH RECURSIVE form. My point here was: we definitely support the standard. We don't do the string literal bit for functions just because we like to be different. We do it because our extensibility features require it. Of course, SQL/PSM is a different beast than all the rest of the PLs, because it is standard, so I am sure that we will want to implement the standard syntax (no string literal) when we have SQL/PSM. But implementing no- string-literals before we get full SQL/PSM support would be pointless, because there are so many other things that are not standard in that area. Simply removing the quotes (which is what you are requesting) would not take our standards compliance much further. -- Alvaro Herrera http://www.CommandPrompt.com/ The PostgreSQL Company - Command Prompt, Inc. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
