the patch include:

- rename ichar() to chr() (discussed with Tom)

        - add docs for oracle compatible routines:

                btrim()
                ascii()
                chr()
                repeat()

        - fix bug with timezone in to_char()

        - all to_char() variants return NULL instead textin("")
          if it's needful.

 The contrib/odbc is without changes and contains same routines as main
tree ... because I not sure how plans are Thomas with this :-)

This effectively one line patch should fix the fact that
foreign key definitions in create table were erroring if
a primary key was defined.  I was using the columns
list to get the columns of the table for comparison, but
it got reused as a temporary list inside the primary key
stuff.
