Обсуждение: pgsql: Doc: mention foreign keys can reference unique indexes
Doc: mention foreign keys can reference unique indexes We seem to have only documented a foreign key can reference the columns of a primary key or unique constraint. Here we adjust the documentation to mention columns in a non-partial unique index can be mentioned too. The header comment for transformFkeyCheckAttrs() also didn't mention unique indexes, so fix that too. In passing make that header comment reflect reality in the various other aspects where it deviated from it.
