Thread: pgsql: Adjust parser so that POSTQUEL-style implicit RTEs are stored

Log Message:
-----------
Adjust parser so that POSTQUEL-style implicit RTEs are stored with
inFromCl true, meaning that they will list out as explicit RTEs if they
are in a view or rule.  Update comments about inFromCl to reflect the way
it's now actually used.  Per recent discussion.
