Update of /home/projects/pgsql/cvsroot/pgsql/src/backend/optimizer/prep
from hub.org:/home/projects/pgsql/tmp/cvs-serv64116
Modified Files:
preptlist.c
----------------------------- Log Message -----------------------------
Make update lists like 'UPDATE tab SET foo[1] = bar, foo[3] = baz'
work as expected. THe underlying implementation is essentially
'SET foo = array_set(foo, 1, bar)', so we have to turn the items
into nested invocations of array_set() to make it work correctly.
Side effect: we now complain about 'UPDATE tab SET foo = bar, foo = baz'
which is illegal per SQL92 but we didn't detect it before.
