/**

* The migration "Version0161Date20190902103701" created a unique index for account_id and name without
|
|
* specifying a name. Unfortunately, this resulted in different index names depending on the table
|
|
* prefix, which means we now have to loop through the indexes to find the correct one.
|
|
*
|
|
* The index on account_id and name were supposed to be dropped in "Version3500Date20231115184458",
|
|
* but this did not work on every setup due to the name mismatch caused by different table prefixes.
|
|
*
|
|
* Although it is not recommended to change migrations after release,
|
|
* we are updating this one with a safeguard to drop any existing index on account_id and name.
