The statement:
'CREATE EXTENSION uuid-ossp'

just gives me a syntax error:

ERROR:  syntax error at or near "-"
LINE 1: CREATE EXTENSION uuid-ossp
                             ^
********** Fehler **********

ERROR: syntax error at or near "-"
SQL Status:42601
Zeichen:22

Obviously "CREATE EXTENSION" expects underscores instead of hyphens.

I had to replace the hyphen in file names and in the scripts to make the
module work.
