Description
When using the SQLite adapter, tables can be created with a multi-column primary key.
Trying to change the primary key to a multi-column one afterwards fails (whether it previously was a single-column or multi-column one) with InvalidArgumentException "Invalid value for primary key: [...]".

Research direction
Start by reproducing the failure in the SQLite adapter when changing either a single-column or multi-column primary key to a multi-column key. Trace the validation that raises InvalidArgumentException for the primary-key value. Done means both primary-key change cases work for SQLite without that exception, with coverage for the reported behavior.
