in method SchemaDumper#table
there are these three lines:
[snip]
column_specs = columns.map do |column|
raise StandardError, “Unknown type ‘#{column.sql_type}’
for column ‘#{column.name}’” if @types[column.type].nil?
next if column.name == pk
[snip]
Shouldn’t it test for column.name == pk before
@types[column.type].nil?
column.type is nil for primary keys as far as I can see in the
connection adapters (its value is got from
ConnectionAdapters::Column.simplified_type).
