In #167 we added support for specifying a postgres `search_path`, which is used to store the `schema_migrations` table. However, if the schema does not already exist it will cause an error.
In this PR we automatically create the first schema in the `search_path` if it does not exist.
Instead of hardcoding `schema_migrations` table to the `public` schema, add support for specifying a schema via the `search_path` URL parameter.
**Backwards compatibility note**: If anyone was using the previously undocumented `search_path` behavior (affecting migrations themselves, but always storing the `schema_migrations` table in `public`), you will need to either prepend `public` to your `search_path`, or migrate your `schema_migrations` table to your primary schema:
```sql
ALTER TABLE public.schema_migrations SET SCHEMA myschema;
```
Closes#110
Prior to this commit, we released two linux binaries:
* `dbmate-linux-amd64` (built with cgo, dynamically linked)
* `dbmate-linux-musl-amd64` (built without cgo, statically linked, no sqlite support)
The statically linked binary is desirable for alpine linux users (or anyone else using musl libc or minimal docker images). The original reason for having two separate binaries was that the easiest method to create a static binary for go is to set `CGO_ENABLED=0`, but unfortunately this also prevented us from building sqlite (which requires cgo).
With this commit, all linux and windows binaries are explicitly statically linked while leaving cgo enabled. Hat tip to https://www.arp242.net/static-go.html which explained the necessary flags to enable this.
As an added bonus, the `dbmate` docker image now now uses a `scratch` base rather than `gcr.io/distroless/base`, reducing the image size from 26.7 MB to 9.8 MB.
Extending the `dbmate status` command with the ability to set an exit code or quiet output, for use in scripts.
Flag names were copied from `git diff` command.
✨ When using dbmate as a container, since the base image is distroless, we can't do `dbmate up && dbmate wait`, which makes config a bit more cumbersome (e.g. in kubernetes an extra initContainer).
Closes#111Closes#112
Building with `CGO_ENABLED=0` results in a binary which can run on Alpine linux (with musl libc), but it also disables SQLite support.
Adding an additional target allows people to decide this tradeoff for themselves.
