r@ c @ s$ e Zd ZdZdZdd� Zdd� ZdS )r= a� Wrap around a sqlalchemy text() construct in such a way that
we appear like a column-oriented SQL expression to an Index
construct.
The issue here is that currently the Postgresql dialect, the biggest
recipient of functional indexes, keys all the index expressions to
the corresponding column expressions when rendering CREATE INDEX,
so the Index we create here needs to have a .columns collection that
is the same length as the .expressions collection. Ultimately
SQLAlchemy should support text() expressions in indexes.
