Group `CREATE TABLE` statements

[grzegorzk]

When some tables reference each other through foreign keys it would be good to first issue CREATE TABLE statements and then, once all tables had been created, add any constraints/foreign keys.

There is more fundamental issue with statements generated by the tool that rely each on other.

Example - I can have some functions that operate on tables and some other functions that I then use to build indexes and if order of CREATE statements is incorrect then the script will fail.

Not to mention one function may depend on another function.

@grzegorzk did you solve this case?

I have similar issue: table_child references table_parent with foreign key but table_child is created first and then table_parent
