db: removing deprecated GLOBAL from temp table...

removing deprecated GLOBAL from temp table creation

Postgres 9.2 makes the GLOBAL keyword in temp table creation deprecated.
http://www.postgresql.org/docs/9.2/static/sql-createtable.html :

TEMPORARY or TEMP :
    Optionally, GLOBAL or LOCAL can be written before TEMPORARY or TEMP.
This presently makes no difference in PostgreSQL and is deprecated; see
Compatibility.

This patch removes this keyword for db code.
