If a table name is a reserved word
then the PostgreSQL error message syntax error at or near "." may arise.
Example: user is a reserved word. The query
will therefore fail at the . of user.jsonb.
Option 1: Quote identifiers as described in https://www.postgresql.org/docs/current/sql-syntax-lexical.html#SQL-SYNTAX-IDENTIFIERS
Option 2: Disallow reserved words as table names. Add a check to RMB's SchemaMaker that throws an exception if any table name is a reserved word in PostgreSQL or SQL-92.
