Fix several schema dump test for postgres

https://github.com/rails/rails/blob/7-1-stable/activerecord/lib/active_record/connection_adapters/mysql2/database_statements.rb#L21

https://github.com/rails/rails/blob/7-1-stable/activerecord/lib/active_record/connection_adapters/postgresql/database_statements.rb#L63

there is diference between mysql/sqllite and postgres internal_exec_query method arity
however due default values is not a issue at least for AR 7.1

some error example:

Error: test_schema_dump(PostgresSchemaDumpTest): ArgumentError: unknown keywords: :allow_retry, :materialize_transactions
/home/jessec/bryk/vendor_gems/stable/activerecord-jdbc-adapter/lib/arjdbc/abstract/database_statements.rb:37:in `internal_exec_query'
/home/jessec/.gem/jruby/3.1.4/gems/activerecord-7.1.3.4/lib/active_record/connection_adapters/postgresql/schema_statements.rb:549:in `foreign_keys'
