Feature Requests

would love to see an option to index a table not only in btree but also as hashmap. (like hash index on postgres https://www.postgresql.org/docs/current/hash-index.html) please please please add this

Like `try_insert` except it's `try_update`: ``` // Pseudocode bool try_update(ctx, primary_key_value, value): if ctx.primary_key_column.try_find(primary_key_value): // Row with a matching primary key column exists ctx.primary_key_column.delete(primary_key_value) ctx.primary_key_column.insert(primary_key_value, value) else: // The row with the matching primary key didn't exist return false ```
