Doc: remove misleading info about ecpg's CONNECT/DISCONNECT DEFAULT.
As far as I can see, ecpg has no notion of a "default" openconnection. You can do "CONNECT TO DEFAULT" but that just specifiesletting libpq use all its default connection parameters --- theresulting connection is not special subsequently. In particular,SET CONNECTION = DEFAULT and DISCONNECT DEFAULT simply act on aconnection named DEFAULT, if you've made one; they do not havespecial lookup rules. But the documentation of these commandsmakes it look like they do.Simplest fix, I think, is just to remove the paras suggesting thatDEFAULT is special here.Also, SET CONNECTION *does* have one special lookup rule, whichis that it recognizes CURRENT as an alias for the currently selectedconnection. SET CONNECTION = CURRENT is a no-op, so it's prettyuseless, but nonetheless it does something different from selectinga connection by name; so we'd better document it.Per report from Sylvain Frandaz. Back-patch to all supportedversions.Discussion:https://postgr.es/m/169824721149.1769274.1553568436817652238@wrigleys.postgresql.org
