There are so many of these (172) that it becomes a real pain to add them all. But if you need one, please ask (open an issue) and I'll add it for you.
### Known Issues
#### Sqlite Constraint Issues (Foreign or Unique Key)
First you need to locate your database file. The gossip directory is under this path: https://docs.rs/dirs/4.0.0/dirs/fn.data_dir.html The database file is `gossip.sqlite`. Then you need to install `sqlite3` on your system.
Using `sqlite3` on your database file, the following kind of SQL can help you identify rows that violate foreign key constraints.
##### Error: Sql(SqliteFailure(Error { code: ConstraintViolation, extended_code: 2067 }, Some("UNIQUE constraint failed: person_relay.person, person_relay.relay")))
You can find which rows are duplicated using: `select a.person, a.relay FROM person_relay a INNER JOIN person_relay b WHERE a.person=b.person AND a.relay=b.relay AND a.rowid!=b.rowid;` You'll need to delete one row from each pair (by rowid so you don't delete both of them).
