Update of /home/projects/pgsql/cvsroot/pgsql/src/backend/parser
from hub.org:/home/projects/pgsql/tmp/cvs-serv95731
Modified Files:
parse_clause.c
----------------------------- Log Message -----------------------------
Parse JOIN/ON conditions with the proper visibility of input columns,
ie, consider only the columns coming from the JOIN clause's sub-clauses.
Also detect attempts to reference columns belonging to other tables
(which would still be possible using an explicitly-qualified name).
I'm not sure this implements the spec's semantics 100% accurately, but
at least it gives plausible behavior.
