RisingWave Community - Why are quotes necessary when querying a column in a Kafka table with schema support?

In PostgreSQL, identifiers are considered case-insensitive unless quoted.
When creating a table with a schema in CAPS, such as { "FOO": string, "BAR": int }, the column names become case-sensitive.
Querying a column without quotes may result in the column name being cast to lowercase, causing the query to fail.
Using quotes around the column name, like SELECT "foo" FROM foobar;, ensures that the query references the correct case-sensitive column name.
This behavior is standard in PostgreSQL and helps prevent ambiguity in column names when querying.
