Description
Only occurs when creating a table.
Any SqlInt64 type is assumed to be a SERIAL8 type. So if you have something like:
User
age Int64
Then (I thinK) age would be SERIAL8 or an autoincrementing value. I don't think this makes a huge difference, but it does result in a wasteful sequence being created.
dang we really gotta have better story around ID types

Research direction
Start by locating the PostgreSQL table-creation mapping for SqlInt64 and inspect how SERIAL8 is selected. Verify the generated schema for an Int64 field such as User.age, then add or update coverage so ordinary Int64 fields do not create an unnecessary autoincrementing sequence.
