Problem Description:
--------------------
Case statements in selects with table joins causes psql to abort

--------------------------------------------------------------------------

Test Case:
----------
The following works:

1)   SELECT OrderTypeID, invoiceid, (CASE OrderTypeID WHEN 1 THEN 'OrderTypeName'::text ELSE 'iname'::text END) as
invdesc
   FROM Invoice
   WHERE invoiceid = 16476;

The following causes psql to abort:

2)  SELECT i.OrderTypeID, i.invoiceid, il.memberid, (CASE i.OrderTypeID WHEN 1 THEN 'OrderTypeName'::text ELSE
'iname'::textEND) as invdesc 
   FROM Invoice i, InvoiceLines il
   WHERE i.invoiceid = 16476 and i.InvoiceID = il.InvoiceID and il.memberid = 685;

The following causes psql to abort:

3)   SELECT OrderTypeID, invoiceid, (CASE OrderTypeID WHEN 1 THEN 'OrderTypeName'::text ELSE 'iname'::text END) as
invdesc
   FROM InvoiceInvoiceLines
   WHERE invoiceid = 16476;

InvoiceInvoiceLines is view that basically looks just like #2 about
