Run Migration not in a transaction about tern

[jackc]

That setting isn't wired into the CLI. No reason not to, just no one ever did it. 🤷

Would there be a filename convention to disable running the Migration in a transaction that would be suitable for you?
If so than I might make a PR for it.
something like:
002_create_table_foo.no_tx.sql?

Other tools generally enable transactions with the .tx.sql suffix instead of disabling them, but doing that would break backwards compatability.

Is this a feature you would like to have?

[jackc]

The overall feature is fine, but I would probably lean toward a magic comment rather than something as part of the file name. That would allow conveniently adding more per migration behavior flags.

It's not just the CLI, it's a bit clunky to use in code too. This struct is not exported:

tern/migrate/migrate.go

Line 107 in 0c8ea39

type defaultMigratorFS struct{}

So if I want to set DisableTx in the MigratorOptions passed to NewMigratorEx, I have to reimplement the default file system migrator. Regardless of #43 it could be good to expose this struct for the future (unless MigratorFS will always be the only option).

This should be resolved on v2-dev with b23e02f.
