Working on a project I ran into the documentation for customizing the Foreign Key.
The docs read:
// https://sequelize.org/master/manual/assocs.html
// For example, to use UUID as the foreign key data type instead of the default (INTEGER), you can simply do:
const { DataTypes } = require("Sequelize");
Foo.hasOne(Bar, {
foreignKey: {
// name: 'myFooId'
type: DSometimes it is needed to store compressed data in the DB. Unfortunately not all the DBs have built-in compression and FUSE compressed FSes are not available for every OS. So it may make sense to store compressed binary blobs in the DB.
Unfortunately when one sees them in DBeaver he sees them compressed, but often they are needed uncompressed. So it'd be nice to have a feature to decompress the
Although RULE is not listed as an allowed privilege on https://www.postgresql.org/docs/current/functions-info.html it turns out that PG supports a query like this
select has_table_privilege('table'::regclass::oid, 'RULE')
Some tools rely on this. We can implement it in CRDB by always returning false, since CRDB does not have RULE privileges.

We already have some scripts in the scripts directory. It would be good to run them for every PR.
This is also a great task for beginners.

Currently we only support Upsert for CockroachDB. Implementing same for MySQL should be pretty straightforward as well.
Wonder if we can also use INSERT ON CONFLICT UPDATE for PostgreSQL to ensure operation with same signature also works.
Add test case for DataSourceConfiguration.equals() when dataSourceClassName not equal.

Describe the bug
Using a time dimension on a runningTotal measure on Snowflake mixes quoted and unquoted columns in the query. This fails the query, because Snowflake has specific rules about quoted columns. Specifically:
- All unquoted column names are treated as upper case
- Quoted column names are case sensitive.
So "date_from" <> date_from

When I try to connect dolt server using golang's go-sql-driver/mysql driver in multiple heads mode, It seems that go-sql-driver/mysql driver does't support database with a sub name. DSN string format in go-sql-driver/mysql like [username[:password]@][protocol[(address)]]/dbname[?param1=value1&...¶mN=valueN]. When dbname is "mydb", It works, but not work when dbname is "mydb/feature-branch".
