:tags: bug, autogenerate, sqlite
:tickets: 1165
Fixed issue where indexes on SQLite which include SQL expressions would not
compare against themselves correctly, generating false positives.
SQLAlchemy as of version 2 has no support for reflecting expression based
indexes on SQLite; so for now, the behavior is that SQLite expression-based
indexes are ignored for autogenerate compare, in the same way that
PostgreSQL expression-based indexes were ignored for the time that
SQLAlchemy did not support reflection of such indexes (which is now
supported in SQLAlchemy 2.0 as well as this release of Alembic).
