Let's say we have a problem with DSN which leads to dialector initialize error. However DB connection is not created and for some reason line 184 error provides <nil> even though "db" doesn't exist.
Previously, this code leads to:
panic: runtime error: invalid memory address or nil pointer dereference
This fix now doesn't attempt to close non-existant database connection and instead continues, so the proper error is shown. In my case:
[error] failed to initialize database, got error default addr for network 'localhost' unknown
* max identifier length changed to 63
* default maxIdentifierLength is 64
* renamed License to LICENSE (#6336)
* Added support of "Violates Foreign Key Constraint" (#6329)
* Added support of "Violates Foreign Key Constraint"
Updated the translator and added the support of "foreign key constraint violation". For this, this error type is needed here.
* changed the description of ErrForeignKeyViolated
* refactor: error translator test (#6350)
