Description
https://github.com/luckyframework/avram/blob/main/src/avram/migrator/create_index_statement.cr
Not sure how this would look, but maybe something like
```crystal
create_index :servers, [:enabled, :kind] where: ServerQuery.new.enabled(true)
# CREATE INDEX ... ON users (enabled, kind)
# WHERE enabled = true
```
The only thing with this is it ties your migrations to `ServerQuery`. If you remove that, then this breaks.

Research direction
Start with src/avram/migrator/create_index_statement.cr and trace how index definitions become SQL. Compare the proposed create_index call with the requested PostgreSQL partial-index output, then resolve how the WHERE condition should be represented without making migrations depend on a removable ServerQuery. Done means the API and generated SQL behavior are defined and covered by appropriate tests.
