race detected in ```schema.Field.Clone()```

[Nick Blaskey]

Hello,

Using Bun one of our tests spawns goroutines which have insert and select queries. Around 5% of the time the race detector will find this issue.

Please let me know if this is a known issue or if there is anything to do to workaround this. I'm also happy to contribute a fix if the project would be okay with that too. Thanks.

This is using postgres and 1.17 version of Bun and 1.22 of Go but have observed the issue on Bun 1.14.

I've looked at #919 but still seeing the issue on 1.17

[Vladimir Mihailenco]

Presumably this should be fixed by 9052fc4 . Please try v1.2.0

[Nick Blaskey]

Thanks so much! That seems to have resolved the issue!
