Could we support CockroachDB, so we get clustering and region clustering in order to support the privacy laws.

support CockroachDB.
Its got multi region clustering and so conforms to the various privacy laws. A lot easier.

explanation: https://www.cockroachlabs.com/blog/introducing-super-regions/

Nature of bug

The Issue is the migrate command and pg_advisory_lock:
golang-migrate/migrate#703

stencil server migrate fails:

db migrator: try lock failed in line 0: SELECT pg_advisory_lock($1) (details: pq: unknown function: pg_advisory_lock())

The driver ( github.com/jackc/pgx/v4 ) is fine and works great with cockroach.

source of bug:

package postgres

import (
	"context"
	"embed"
	"fmt"
	"log"
	"net/http"

	"github.com/golang-migrate/migrate/v4"

## Reproduction of bug

here is single server.

.env
```sh
COCKROACH_SRC_DATA_FSPATH=$(PWD)/.data/cockroach
COCKROACH_SRC_LISTEN_ADDRESS=localhost:26257
COCKROACH_SRC_HTTP_ADDRESS=localhost:8080
# cluster ( i you want it )
COCKROACH_SRC_JOIN_ADDRESS=localhost:26257,localhost:26258,localhost:26259

start ( single cockroach node ):
cockroach runs on all desktops btw. you don't have to use docker.

cockroach start --insecure --store=node1 --listen-addr=localhost:26257 --http-addr=localhost:8080 --join=localhost:26257,localhost:26258,localhost:26259 --background

config:
