generate_sql_schema - sql_type_statement unused

[rokf]

Hello,

While checking out the source code of the generate_sql_schema function I've noticed that there's a sql_type_statement variable that isn't used.

It seems to have been added for the same purpose as sql_data_types but isn't used anymore (or never was, didn't check the history)?

Cheers!
