It looks like Spanner already supported their own SQL interface. So are there significant differences between their Google SQL syntax and the PostgreSQL syntax?

Looks like the docs are live alongside the announcement –

"The PostgreSQL language in Cloud Spanner": https://cloud.google.com/spanner/docs/postgresql/overview

"PostgreSQL interface" under the Concepts section: https://cloud.google.com/spanner/docs/postgresql-interface
