// Filter is an interface to filter SQL
type Filter interface {
--- Do(sql string) string
+++ Do(ctx context.Context, sql string) string
}
```
### Adds a `Context` parameter to the `Do` method of the Filter interface.
Developers can rewrite SQL through the `Filter` `Do` method and **need to get the necessary data from the Context** to assist.
For example, get user information through `Context`, so that different users can use different tables. Another example is to get the flags through `Context` to add annotations to the SQL, and use the annotations to let the subsequent `DB-Proxy` to achieve read/write separation.

When dropping indexes in Postgres if the index is non-regular we
should not attempt to regularise the index name as it is already correct.

This should solve #1954 and adds some tests for it. I will note I'm not 100% clear on whether there are other edge cases that should be covered here. From what I understand the only standard SQL way to escape single quotes is to double them, which shouldn't cause any problems with this, but if some SQL flavors allow other kinds of escaping, for instance, that would probably need to be covered too for ideal results.
