`sea-orm-cli generate entity` panics with `"not implemented"` on `Decimal` column (2.0.0-rc.41)

[jvcByte]

Description

sea-orm-cli generate entity panics with "not implemented" when processing a Decimal column using the --entity-format expanded option.

Steps to Reproduce

1. Run the following command (using a Neon Postgres database), replace database url with actual database url:

sea-orm-cli generate entity \
  -o database/entity/src/ \
  -u "postgresql://..." \
  --entity-format expanded \
  --max-connections 1

2. The command processes several tables successfully, then fails on the exercises table.

Expected Behavior

The CLI should successfully generate entity files for all tables, including those with Decimal columns.

Actual Behavior

Generation fails with a panic:

thread 'main' (368462) panicked at /home/.../sea-orm-codegen-2.0.0-rc.41/src/entity/column.rs:209:22:
not implemented
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
Aborted (core dumped)

It fails specifically while processing this column in the exercises table:

• pass_mark: Option<Decimal>

Reproduces How Often

Always (on this schema).

Workarounds

• Use --entity-format dense instead of expanded (recommended for SeaORM 2.0 anyway).
• Manually write entities using the new #[sea_orm::model] macro.

Versions

• sea-orm-cli: 2.0.0-rc.41
• sea-orm-codegen: 2.0.0-rc.41
• Database: PostgreSQL (Neon serverless)
• OS: Linux

[Huliiiiii]

We support Decimal, so the issue likely happened while generating another column. Could you provide the definition of the exercises table?
