Syntax error at or near "." because table name is reserved word

If a table name is a reserved word
https://www.postgresql.org/docs/current/sql-keywords-appendix.html
then the PostgreSQL error message syntax error at or near "." may arise.

Example: user is a reserved word. The query

select * from diku_mod_inventory_storage.user where user.jsonb is not null;

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
Example:

select * from "diku_mod_inventory_storage"."user" where "user".jsonb is not null;

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.
