Sometimes 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

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: D

There are several optimization the execution engine can perform when evaluating LIKE patterns with %, which matches zero or any number of any character. For example, see #80073.

Sequential %s can prevent these optimizations, but they are semantically equivalent to a single %, so the optimizer should normalize them to a single %.

For example:

-- The following expressions 

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.

Hi community,

This issue is for WeOpen-Star

Add unit test for ClusterContextManagerCoordinator.renew(final SchemaDeletedEvent event).

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.

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

The JSON response sent back over HTTP doesn't encode certain characters correctly.

For example, if a value in a string column contains the char \1 the byte value is copied verbatim in the response, breaking the client:

>>> json.loads('"\1"')
...
json.decoder.JSONDecodeError: Invalid control character at: line 1 column 2 (char 1)
