Dean Rasheed 88327092ff Add support for INSERT ... ON CONFLICT DO SELECT. ... This adds a new ON CONFLICT action DO SELECT [FOR UPDATE/SHARE], which returns the pre-existing rows when conflicts are detected. The INSERT statement must have a RETURNING clause, when DO SELECT is specified. The optional FOR UPDATE/SHARE clause allows the rows to be locked before they are are returned. As with a DO UPDATE conflict action, an optional WHERE clause may be used to prevent rows from being selected for return (but as with a DO UPDATE action, rows filtered out by the WHERE clause are still locked). Bumps catversion as stored rules change.
