Index migration is generated with parameter

[alicelepadat]

Hello

I defined an index with new version syntax using where:

 systemNameIndex: uniqueIndex('system_name_unique_idx').on(table.name).where(eq(table.type, 'SYSTEM'))

but the migration query is generated with a parameter like this:

CREATE UNIQUE INDEX IF NOT EXISTS "system_name_unique_idx" ON "group" USING btree ("name") WHERE "group"."type" = $1;

It's annoying because every time I want to generate a new migration this index is being dropped and then regenerated an the migration fails with: PostgresError: there is no parameter $1

$1 should be 'SYSTEM' in my case instead.

Is this a bug?
