[❗❗ correctness]
Ensure that the groups column is of a type that supports GIN indexing, such as jsonb or array. Using GIN on unsupported types can lead to unexpected behavior or performance issues.

[performance]
The use of a GIN index on the groups array field is appropriate for improving query performance involving array operations. However, ensure that the pg_trgm extension is enabled in your PostgreSQL database if you plan to use trigram-based searches with this index. Without it, certain operations may not perform as expected.
