-# The ORDER BY matching algorithm is three steps:
-# 
-#   (1)  If the ORDER BY term is an integer constant i, then
-#        sort by the i-th column of the result set.
-# 
-#   (2)  If the ORDER BY term is an identifier (not x.y or x.y.z
-#        but simply x) then look for a column alias with the same
-#        name.  If found, then sort by that column.
-# 
-#   (3)  Evaluate the term as an expression and sort by the
-#        value of the expression.
-# 
-# For a compound SELECT the rules are modified slightly.
-# In the third rule, the expression must exactly match one
-# of the result columns.  The sequences of three rules is
-# attempted first on the left-most SELECT.  If that doesn't
-# work, we move to the right, one by one.
-#
-# Rule (3) is not in standard SQL - it is an SQLite extension,
-# though one copied from PostgreSQL.  The rule for compound
-# queries where a search is made of SELECTs to the right
-# if the left-most SELECT does not match is not a part of
-# standard SQL either.  This extension is unique to SQLite
-# as far as we know.
-#
-# Rule (2) was added by the changes ticket #2822.  Prior to
-# that changes, SQLite did not support rule (2), making it
-# technically in violation of standard SQL semantics.  
-# No body noticed because rule (3) has the same effect as
-# rule (2) except in some obscure cases.
-#
-
-
-# Test plan:
-#
-#   tkt2822-1.* - Simple identifier as ORDER BY expression.
-#   tkt2822-2.* - More complex ORDER BY expressions.
