MySQL到PostgreSQL架构转换

Question

我试图在以下MySQL to PostgreSQL converter的帮助下自动将旧MySQL表转换为PostgreSQL

现在我不明白或者这个工具工作正常。

例如，我有一个以下MySQL表：

accepted_invitations

有2个外键：

fk_accepted_invitations_invitation_id (accepted_invitations.invitation_id -> invitations.id)

fk_accepted_invitations_location_id (accepted_invitations.location_id -> locations.id)

和2个索引：

PRIMARY(invitation_id)
fk_accepted_trial_invitations_location_id(location_id)

在PostgreSQL中转换后，我有一个下表：

accepted_invitations

有2个约束：

accepted_trial_invitations_pkey (PRIMARY KEY(invitation_id)) 
fk_accepted_trial_invitations_invitation_id (FOREIGN KEY(accepted_invitations.invitation_id -> invitations.id))

和1指数：

accepted_trial_invitations_location_id_idx  ON accepted_invitations USING btree (location_id);

我担心转换后我在PostgreSQL中看不到fk_accepted_invitations_location_id

的外键

是转换器错误还是此FK是冗余的，不应该定义？
