SaveFile("estructura.sch", Exportsch(m_session, "test"));

I'm getting the next error

error: 'Exportsch' was not declared in this scope

It's name is wrong, it should be ExportSch not Exportsch

I think I have to add an include file but I don't know wich one, I added the Sql and PostgreSQL packages to my program.
I had to put an empty database.sch file because if I didn't, I got an error saying the file does not exist.

I'm also getting this messages when I compile the program

CtrlLib: circular 'uses' chain
CtrlLib: circular 'uses' chain

The only required header is SqlSchema.h.
The warnings(or errors) about "circular 'uses' chain"(i've never had such an error) , i think are because you're using "using namespace Upp" twice - once in header and once in .cpp file.

I don't have a PostgreSQL database but i've modified SQLApp example to test ExportSch. The only modifications i've made are in main.cpp.

// line 5
void SchExport()
{
	SaveFile("estructura.sch", ExportSch(SQL.GetSession(), ""));
}

void SQLApp::MainMenu(Bar& bar)
{
	bar.Add("ExportSch", callback(SchExport));
    // ...
}

If you don't get it i may make a small example, but i think it's obvious.

P.S.: use code tags(formating tools) to make your code more readable in posts.
