Steven Hawkins commented on TEIID-4646:
---------------------------------------
[~blafond] This change does not alter the javacc grammar, but it does introduce new
resolver and validation logic to ensure that the functions match the expected usage
pattern, so this is marked as affecting the grammar.
Add engine support for lead/lag aggregate functions
---------------------------------------------------
