Adding a SERIAL or GENERATED ... STORED column

ID: E11

A new column was added with a SERIAL or GENERATED type. This blocks all table access until the table is rewritten. A safer way is: Can not be done without a table rewrite.

Added column id with type that will force table rewrite in .prices. serial types and GENERATED ALWAYS as ... STORED columns require a full table rewrite with AccessExclusiveLock.
