Specify static linking for linux builds

TEMP: Only skip homebrew

TEMP: Don't skip publish

Run the `build` workflow on tag push (#520)

We need this to be able to create a release.

Allow configuration of batch delay (#410)

You can now configure a delay after each batch has completed. It can be
configured in three ways:

* The `--backfill-batch-delay` CLI parameter
* The `PGROLL_BACKFILL_BATCH_DELAY` environment variable
* The `roll.WithBackfillBatchDelay` functional option

It defaults to 0 if not set and all values should be provided using the
Go [duration format](https://pkg.go.dev/time#ParseDuration).

Closes #168

Support create/drop index with uppercase names (#356)

Fixes #355

Postgres stores index names with uppercase characters in the `pg_index`
catalog using the quoted version of the name. For example:

```
"idx_USERS_name"
```

whereas a lowercase index name would be stored as:

```
idx_users_name
```

This is different to how other object types are stored in their
respective catalogs. For example, table names are stored in
the`pg_class` catalog without quotes, regardless of whether they contain
uppercase characters.

This makes it necessary to strip quotes from index names when retrieving
them from the `pg_index` catalog when building the internal schema
representation.

Run migration tests in a non-`public` schema as part of CI (#279)

Add another dimension to the test matrix so that migration tests are run
in both the `public` and a non-`public` schema.

#276 made it possible to run
migration tests in schema other than `public`. Doing so highlighted some
issues that are fixed by #278.

Fixes #273.

Use org-level `GIT_TOKEN` for brew tap update (#215)

As described in the GoReleaser docs:
https://goreleaser.com/errors/resource-not-accessible-by-integration/

Specify the token to use for pushing to the tap

Use autogen `GITHUB_TOKEN` (#214)

* Change the `GITHUB_TOKEN` used by the `Build` workflow to the default
one.
* Add the necessary scopes to the token to allow it to create releases
and push images to GHCR.
